Abstract:
This study proposed an intelligent algorithm based on digital image processing and character recognition to address the current situation in which the National Medical Products Administration promulgated the relevant regulations on the complete prohibition of the use of mercury sphygmomanometers in 2020 and the currently widely used electronic sphygmomanometers need to undergo regular verification and quality testing. The intelligent algorithm made it possible to automatically acquire the electronic sphygmomanometer indication value during quality assurance or verification. The images of the electronic sphygmomanometer were captured using a Raspberry Pi-connected video camera head; in the software development, automatic detection of the electronic sphygmomanometer's indication value was achieved by running the computer vision-based OpenCV library on the Raspberry Pi and utilizing image preprocessing techniques like scale transformation, grayscale conversion, Gaussian smoothing and edge detection, and character segmentation. The development of intelligent devices for the automatic verification of electronic sphygmomanometers has a technical foundation in the research and design of the digital recognition algorithm, and it has a certain reference value for character recognition of electronic instruments or the creation of automatic instrument indication value recording devices.

Abstract:
This paper investigated mercury (Hg) flows and stock through mercury thermometers and sphygmomanometers in Thailand for 2010 using Material Flow Analysis (MFA) based on mass balance principles. All calculations in this study are based on data from hospital surveys and reliable secondary data sources. This study indicates that all thermometers and sphygmomanometers used in Thailand were only imported. Mercury contained in thermometers and sphygmomanometers was about 1,675 kg and 5,375 kg respectively. During the use phase, thermometers can release roughly 70% of Hg into the environment (air and water) while no emissions were emitted from sphygmomanometers. This study also shows that about 20-30% of mercury thermometer and sphygmomanometer waste were disposed of in landfills and incinerators. Hg can be released into air, land, and water at approximately 53%, 35%, and 12% respectively. According to our scenario analysis, it shows that phasing out Hg medical-based devices combined with preventing the breakage and spillage of Hg-thermometers can give higher potential reduction of Hg in Thailand.

Abstract:
Nosocomial infections are infections that patients acquire while receiving treatment for other health conditions within a healthcare setting or facility. This study aims to determine the level of awareness of healthcare providers on the role sphygmomanometers play in the spread of nosocomial infections and to isolate microorganisms in sphygmomanometer cuffs used in healthcare facilities. A structured, self-administered questionnaire was designed and administered to healthcare practitioners of two tertiary hospitals and community pharmacies in Benin City. Microbial contamination of sphygmomanometer cuffs was investigated following the standard isolation and identification techniques for microorganisms. A total of 217 responded; 27.2% pharmacists, 33.2% doctors and 39.6% nurses. The majority (50.2%) were between the ages of 20 – 30 years. 65.4% were females and 51.6% were single. Ninety-four percent (94%) of the total respondents said that microorganisms are present in the inner cuffs of sphygmomanometers, 76% said microorganisms on the cuffs are sources of nosocomial infections while 80.6% said patients can be infected with the use of sphygmomanometers. A total of 192 swabbed samples were collected from 64 cuffs in the healthcare facilities, 46.5% were bacteria and 53.5% fungi. The most isolated organisms were candida species 42(21%), Staphylococcus aureus 41(20.5% of which 28(68.3%) were methicillin resistant.), Mucor 34(17%), Aspergillus species 23(11.5%). Ninety four percent (94%) of respondents had good knowledge that blood pressure cuffs play a role in the spread of nosocomial infections. The sphygmomanometer cuffs were contaminated with pathogenic microorganisms implicated in nosocomial infections.

Abstract:
Background: heart rates generated by pulse oximeters and electronic sphygmomanometers in acutely ill patients may not be the same as those recorded by ECG Methods: heart rates recorded by an oximeter and an electronic sphygmomanometer were compared with electrocardiogram (ECG) heart rates measured on acutely ill medical patients. Results: 1010 ECGs were performed on 217 patients while they were in the hospital. The bias between the oximeter and the ECG measured heart rate was -1.37 beats per minute (limits of agreement -22.6 to 19.9 beats per minute), and the bias between the sphygmomanometer and the ECG measured heart rate was -0.14 beats per minute (limits of agreement -22.2 to 21.9 beats per minute). Both devices failed to identify more than half the ECG recordings that awarded 3 NEWS points for heart rate. Conclusion: Heart rates of acutely ill patients are not reliably measured by pulse oximeter or electronic sphygmomanometers.

Abstract:
A sphygmomanometer is a tool for measuring blood pressure that is often used in the medical world. Sphygmomanometers are generally divided into 2, namely analog and digital sphygmomanometers. In modern times now Android smartphones have developed with various features that are already very sophisticated. Therefore, the author wants to design a digital sphygmomanometer that can measure blood pressure and provide a history of measurement results so that the public or patients candetermine the state of their blood pressure. To present this tool in this study, the author will try to integrate a digital blood pressure measuring instrument with IOT (internet of things) so that it becomes a blood pressure detection and monitoring tool. NodeMCU ESP8266 will be used to process data and also serve to connect to the internet. Then, the sensor used is the MPX5050GP sensor as a pressure measurement tool and then the pressure calculation data from the sensor is sent to Firebase which acts as a database, and later it can be accessed and monitored via a smartphone. Theresults of testing the sphygmomanometer tool that the researcher made and the testing of the comparative sphygmomanometer tool. On average, this test gets an accuracy difference of approximately 1%.

Abstract:
IntroductionThe development of more accurate algorithms has encouraged the replacement of sphygmomanometers with automatic blood pressure (BP) monitors in adults. From the perspective of health professionals, these technologies are advantageous for their practicality and are less susceptible to observer errors, and many devices validated by standardized protocols are available for both clinical and home use. However, adherence to these technologies also depends on patient acceptance. No studies to date have examined patient preference for BP measurement in the Brazilian population, although Brazil has undertaken initiatives to replace auscultatory measurement with oscillometric measurement. This study aims to analyze patient preferences between sphygmomanometers and automatic monitors for BP measurement.MethodsAn analytic study was conducted with 93 subjects in a Brazilian outpatient care facility. A random sampling method was used to select participants. After obtaining informed consent, all subjects had their BP measured using a sphygmomanometer and then an automatic monitor for clinical use, both in a quiet room after 10 minutes rest. A structured interview on discomfort and preferences was then conducted. An unpaired t-test and a chi-square test were used.ResultsThe mean age was 39.11 (±14.22) years. Minor discomfort was identified when an automatic monitor was used (2.34 versus 2.52). Confidence was higher with the sphygmomanometers (73.11%), and 60.21 percent preferred this technology. There was no association between gender and preferences (p = 0.88), but an association with age was identified. The average age of subjects who preferred sphygmomanometers was higher compared to those who preferred automatic monitors (p < 0.05).ConclusionsThis study revealed that, although BP measurement using automatic monitors is less uncomfortable, patients rely more on sphygmomanometers. Results show that preference is related to age, as younger people tend to prefer automatic monitors. The findings of this study indicate the need to widely disseminate information regarding the accuracy of automatic monitors among patients, especially older ones, in order to make them part of the decision-making process for replacing sphygmomanometers with automatic monitors.

Abstract:
Background: Hospital acquired infections (HAIs) are infections that patients acquire while receiving treatments for other conditions. Studies have shown that stethoscopes and sphygmomanometers can act as potential sources of these infections in patients accessing treatment in healthcare facilities. This study aimed to increase awareness among health workers in Nigeria of the potentials of stethoscopes and sphygmomanometers to transmit HAIs.Methods: Moist swab sticks were used to collect samples from 38 randomly selected stethoscopes and sphygmomanometers from some departments of four district hospitals. Collected samples were cultured using standard microbiological techniques. In addition, self-designed questionnaire was used to assess the knowledge and practice of doctors and nurses on the roles of stethoscopes and sphygmomanometers in HAIs.Results: About 83.8% of the health workers demonstrated some awareness of the roles of stethoscopes and sphygmomanometers in HAIs. 42.5% cleaned their stethoscopes, while 5% their sphygmomanometers. Staphylococcus aureus, (65.9% of stethoscopes), proteus mirabilis, Pseudomonas aeruginosa (67.6% of sphygmomanometers), Streptococcus and Coliform species were isolated. There was no significant difference between the contamination of stethoscopes and sphygmomanometers by the isolates, except for Pseudomonas aeruginosa (t=3.49, p=0.04).Conclusions: Awareness did not match practice in cleaning the stethoscopes and sphygmomanometers in the four facilities. Staphylococcus aureus and Pseudomonas aeruginosa were the two most common organisms isolated with a significant difference (t=3.49, p=0.04) between stethoscopes and sphygmomanometers in isolation of Pseudomonas aeruginosa. To curb HAIs, health workers need to improve on their practice of cleaning stethoscopes and sphygmomanometers.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO
Observa-se um crescente interesse na determinação da incerteza de medição para a avaliação de conformidade e garantia da qualidade, principalmente nos setores de meio- ambiente, segurança, saúde e indústria, nos quais o resultado da medição é considerado crítico por lidar diretamente com seres humanos. Na medição da pressão arterial, conforme estudos realizados em países como a Austrália, Inglaterra, Turquia e Brasil, observa-se uma grande preocupação com a confiabilidade dos resultados obtidos por esfigmomanômetros mecânicos não invasivos. Nestes estudos, erros de até 4,4 kPa (33 mmHg) foram encontrados nos instrumentos avaliados, contra o valor de erro máximo de 0,53 kPa (4 mmHg) definido na OIML R 16-1:2002. Atualmente, a avaliação da confiabilidade dos esfigmomanômetros mecânicos é obtida considerando apenas o erro de medição, sem considerar a incerteza de medição. Com a motivação de contribuir para a garantia da confiabilidade metrológica dos esfigmomanômetros mecânicos não invasivos, usados mundialmente em hospitais e residências, o presente trabalho tem por objetivo associar a incerteza de medição na avaliação da confiabilidade metrológica destes instrumentos. Para a realização das medições foi montado um aparato envolvendo instrumentos de monitoração ambiental conforme recomendações internacionais (OIML R-16-1:2002) e nacionais (ABNT NBR-14105:1998 e NIEDIMEL- 006). Os dados do presente trabalho foram obtidos por meio de medições diretas em esfigmomanômetros novos e usados utilizando um padrão de pressão. Foram avaliados: o erro de medição, a histerese, o erro fiducial e a incerteza de medição. Os resultados obtidos com o presente trabalho mostram que, em função da incerteza de medição, o erro máximo permissível de 0,53 kPa (4 mmHg) pode não fornecer a confiabilidade adequada. Se for considerado apenas o erro de medição do manômetro conforme a OIML R 16- 1:2002, 60 % dos esfigmomanômetros avaliados foram aprovados. Se for considerado o erro e a incerteza de medição do manômetro, conforme proposto, apenas 12 % dos esfigmomanômetros foram aprovados. Com base nos resultados obtidos no presente trabalho, propõe-se reduzir o erro máximo admissível para estes instrumentos, incorporando a incerteza de medição, sem a necessidade de realizar na prática o seu cálculo. Com base nos resultados do presente trabalho recomenda-se uma revisão na faixa de erro máximo permissível na avaliação da OIML, em conjunto com a proposta de uma nova especificação do manômetro usado nos esfigmomanômetros, com redução do erro intrínseco e melhora de sua resolução.
It is observed an increasing interest on the estimation of measurement uncertainty to deciding on conformity and quality assurance, mainly in the fields of environment, safety, health and industry, in which the measurement results are critical once they directly deal with human beings. According to studies performed in Australia, England, Turkey and Brazil, a great concern is observed with the reliability of the results obtained for blood pressure measurements by noninvasive mechanical sphygmomanometers. In these studies, errors of up to 4,4 kPa (33 mmHg) were obtained in the evaluated instruments, against the value of maximum error of 0,53 kPa (4 mmHg) required by OIML R 16-1:2002. Nowadays, the evaluation of the reliability of these measurement instruments for medical diagnosis is obtained considering only the measurement error (according to OIML R 16-1:2002), without taking into account the measurement uncertainty. Motivated to contribute for the metrological reliability of non- invasive mechanical sphygmomanometers, globally used in hospitals and residences, the present work aims at developing a model to associate the measurement uncertainty on the metrological reliability evaluation of these instruments. In order to perform the measurements with the sphygmomanometers, a set-up were prepared with environmental monitoring according to international recommendation (OIML R-16:2002) and national standards (ABNT NBR-14105:1998 and NIE-DMEL-006). The data of the present work were obtained by means of direct measurements in new and in use sphygmomanometers, utilizing a pressure pattern. Calculation of the following parameters was performed: measurement error, hysteresis, fiducial error and measurement uncertainty. The obtained results show that, as a function of the measurement uncertainty, the maximum permissible error of 0.53 kPa (4 mmHg) can be overcome. Considering the manometer measurement error, according to OIML R 16-1:2002, 60 % of the non- invasive mechanical sphygmomanometers evaluated were approved. When considering not only the measurement error, but also measurement uncertainty of the manometer, only 12% of the non-invasive mechanical sphygmomanometers were approved. Based on the present results, a reduction of the maximum permissible error for these instruments, incorporating the measurement uncertainty, without the need to calculate it in the verification procedure, is proposed. This work recommends not only a review of OIML maximum permissible error for sphygmomanometers, but also proposes a new configuration of the instrument, with reduction of intrinsic error and improvement of resolution.

Resumo: A medida da pressão arterial é uma prática rotineira nas instituições de saúde e, mais recentemente, em muitos lares. Levando em consideração fatores como praticidade e riscos ambientais com a produção e o descarte do mercúrio, vem aumentando a oferta e a utilização sistemática de aparelhos automáticos para essa medida. Mesmo em decorrência das novas tecnologias, normas foram instituídas para garantir a precisão e o desempenho desses aparelhos, passando então por critérios rigorosos a fim de testar sua validação para uso. O presente estudo tem como objetivo avaliar a confiabilidade e o desempenho do aparelho automático de punho, visomat® handy IV, para medida indireta da pressão arterial, de acordo com o Protocolo Internacional da European Society of Hypertension. PI/ESH. Para isso, medidas da pressão arterial sistólica e diastólica em 33 voluntários (15 para a Fase I e mais 18 para a Fase II, contando 99 medidas), foram obtidas usando um esfigmomanômetro de coluna de mercúrio (Unitec®) e um esfigmomanômetro automático (visomat® handy IV). Nove medidas sequenciais no braço/punho entre o esfigmomanômetro de mercúrio e o automático em teste, foram realizadas de acordo com o Protocolo Internacional em suas fases (Fase I, Fase II.a e Fase II.b), além do exame de eletrocardiograma. O aparelho passou na Fase I com 32 medidas para pressão sistólica e 26 para a diastólica, excedendo 25 exigidas, no intervalo de 0-5 mmHg. Já na Fase II.a o aparelho passou, com 64 medidas para a sistólica e não passou na diastólica, atingindo apenas 40 das 60 exigidas. Finalmente, na Fase II.b pelo menos 22 voluntários deveriam ter duas de suas três comparações situadas na faixa até 5 mmHg, o que aconteceu com somente 21 voluntários na sistólica e 12 na diastólica; além disso, no máximo três poderiam ter todas suas comparações acima de 5 mmHg e isso aconteceu com 5 voluntários na sistólica e 12 na diastólica. A média das diferenças mostrou uma discordância entre o esfigmomanômetro de mercúrio e o aparelho automático de 0,5 (±8,5) mmHg para a pressão arterial sistólica e de - 3,8 (±9,1) mmHg para a diastólica, respectivamente. Conclui-se que o esfigmomanômetro automático visomat® handy IV não conseguiu atingir os critérios mínimos do PI/ESH, não sendo recomendado para o uso clínico
Abstract: The measurement of blood pressure is a routine practice in health care institutions and, more recently, at home. Taking into account factors like convenience and environmental risks related to production and discard of mercury, supply and systematic application of automated device for the measurement has increased. As a result of new technologies, standards were established to ensure the accuracy and performance of the devices, which were submitted to strict criteria in order to test its validation for use. This study aims to evaluate the wrist automatic device for indirect measurement of blood pressure, visomat® handy IV, according to the International Protocol of the European Society of Hypertension - IP/ESH. For this, measurements of systolic and diastolic blood pressure in 33 volunteers (15 for Phase I and a further 18 for Phase II, counting 99 measurements) were obtained using a mercury sphygmomanometer (Unitec®) and an automatic sphygmomanometer (visomat® handy IV). Nine sequential measurements with a mercury sphygmomanometer (five, on the arm) and automatic device (four, on the wrist) were performed according to the International Protocol in its phases (Phase I, Phase II.a and Phase II.b), besides the electrocardiogram. The device passed Phase I with 32 measurements for systolic and 26 for diastolic in the range of 0-5 mmHg (25 are required). In Phase II.a, the device reached 64 adequate values for systolic and 40 for diastolic pressure (60 are required). In Phase II.b, at least 22 volunteers should have two of their three comparisons situated in the range up to 5 mmHg, and this occurred with only 21 volunteers in systolic and 12 in diastolic. Moreover, at most three could have all their comparisons above 5 mmHg and this happened to five volunteers in systolic and 12 in diastolic. The mean differences showed a disagreement between the Mercury sphygmomanometer and the automated device of 0,5 (±8,5) mmHg for systolic and - 3,8 (±9,1) mmHg for diastolic, respectively. We conclude that the automatic sphygmomanometer visomat® handy IV failed to achieve the minimum criteria of the IP/ESH, and is not recommended for clinical

O estudo aborda os processos de limpeza e desinfecção dos principais dispositivos de monitoramento não críticos (termômetros, esfigmomanômetro, cabos de eletrocardiograma e oxímetro) considerando a sua participação na transmissão das infecções relacionadas à assistência à saúde. Estes equipamentos têm sido apontados como uma das principais fontes de infecção por bactérias multirresistentes causadoras de surtos infecciosos em ambiente hospitalar portanto, exigem padronização da limpeza e desinfecção, mediante um protocolo que norteie o processo de trabalho. Este estudo teve como objetivos: elaborar um protocolo de limpeza/desinfecção dos principais dispositivos de monitoramento não críticos, com base nas boas práticas e evidências na literatura, e validar este protocolo com avaliação de experts em infecção hospitalar. Trata-se de estudo descritivo e exploratório, que no seu desenvolvimento seguiu as seguintes etapas: revisão integrativa da literatura, elaboração do protocolo de limpeza e desinfecção dos principais dispositivos de monitoramento não críticos e validação do protocolo por experts em infecção hospitalar. A elaboração do protocolo ocorreu a partir das boas práticas identificadas nos estudos selecionados na revisão integrativa, livros, teses, dissertações e documentos de órgãos nacionais e internacionais sobre a temática. Para validação do protocolo foram selecionados cinco experts em infecção hospitalar, de acordo com os critérios de seleção sugeridos no estudo. Após avaliação de cada recomendação do protocolo proposto, em um questionário, foi calculado o grau de concordância entre eles por média ponderada. A partir da análise dos registros dos experts e, considerando o grau de concordância das respostas, foi elaborado o protocolo final. Assim, respondendo aos objetivos do estudo, inicialmente tem-se o protocolo construído a luz do conhecimento científico que foi chancelado por um grupo de experts gerando o protocolo final. Este protocolo é portanto, o produto desta pesquisa e com ele pretende-se padronizar os processos de limpeza e desinfecção destes dispositivos, visando preencher as lacunas do conhecimento teórico/prático identificadas sobre a temática e reduzir os riscos de transmissão de infecção por estes artigos. Este protocolo será proposto à Comissão de Controle de Infecção Hospitalar da Secretaria Estadual de Saúde do Rio de Janeiro, a fim de implementá-lo nas unidades de pronto atendimento 24 horas (UPAs 24hs) testando sua aplicabilidade e futuramente sua eficácia.
The study discusses the procedures of cleaning and disinfection of the main non-critical monitoring devices (thermometers, sphygmomanometer, electrocardiography wires and oximeters wires) considering their participation in the transmission of infections related with health care. These equipments have been identified as the major source of infection by multiresistant bacteria that causes hospital infections, therefore, require standardization of cleaning and disinfection, by using a protocol that guides the work process. This study aims to: develops a protocol for cleaning / disinfection of the main non-critical monitoring devices, based on best practices and evidence in the literature, and validate this protocol with assessment of experts in hospital infections. It is descriptive and exploratory study, which involved the following steps: integrative literature review, development of the protocol for cleaning and disinfection of the main devices of non-critical monitoring and a validation of this protocol by the experts of hospital infection. The protocol development is based on best practices identified in the studies selected in integrative review, books, thesis, dissertations and national and international documents on the subject. To validate the protocol, five experts in hospital infection were selected according to the selection criteria suggested in the study. After evaluating each recommendation of the proposed protocol, in a questionnaire, the degree of agreement was calculated by weighted average. From the analysis of the observations of experts and considering the degree of agreement of answers, a final protocol was developed. So, to answer the aim of this work, first of all, a protocol was developed with scientific knowledge and afterward judged by some experts, which leads to a final protocol. Therefore this final protocol is the result of this study and it is intended to standardize the process of cleaning and disinfection of these devices, fill gaps in theoretical/practical knowledge on the subject and reduce the risk of infection transmission by these objects. These protocol will be proposed to the of Hospital Infection Control Committee at the State Department Health of Rio de Janeiro, to implement it in emergency care unit (called “UPAs 24 hs”) testing its applicability and future effectiveness.

Abstract:
Cardiovascular disease is the leading global cause of mortality and morbidity and high blood pressure (BP) is the single greatest risk factor. Cuff measured BP is used in clinical practice to diagnose and guide management of high BP, with treatment of high BP resulting in a reduction of cardiovascular risk. For these reasons, BP measurement is among the most important medical tests performed, yet the conventional cuff method may be inaccurate. The overall aims of this research were to determine: the accuracy of cuff measured BP; if distinct BP phenotypes exist that relate to cuff BP accuracy and; haemodynamic factors that influence estimation of BP. In study 1 (Chapter 2), the accuracy of cuff measured BP compared with intra-arterial brachial and aortic BP was examined via three individual participant data meta-analyses among data from the 1950’s to 2016. Intra-arterial brachial systolic BP was higher than aortic values. Cuff BP had variable accuracy for measuring intra-arterial brachial and aortic BP, and this significantly influenced correct BP classification. Indeed, the concordance of cuff BP across hypertension categories (normal, pre-hypertension, hypertension stages 1 and 2) compared with intra-arterial brachial BP was 60%, 50%, 53% and 80%, and compared with intra-arterial aortic BP was 79%, 57%, 52% and 76%. In study 2 (Chapter 3), cuff measured BP and intra-arterial BP waveforms from the aorta, brachial and radial arteries were examined in 126 patients undergoing coronary angiography. Four novel BP phenotypes were discovered based on variability in aortic-to-brachial and brachial-to-radial systolic BP amplification. Cuff BP was unable to discriminate between the phenotypes (p>0.5 all comparisons), and among two phenotypes completely missed patients at potentially higher risk due to raised aortic BP. The key findings were confirmed by additional data in 255 patients, supplied by four independent, international collaborators. In study 3 (Chapter 4), intra-arterial BP from 107 individuals undergoing coronary angiography was used to determine the best peripheral BP waveform calibration method for the estimation of aortic BP, as well as haemodynamic factors that may influence accuracy. BP waveforms calibrated with brachial mean arterial BP/diastolic BP estimated aortic systolic BP more accurately than brachial systolic BP/diastolic BP calibration. However, systolic BP amplification had a major influence on the accuracy of estimated aortic systolic BP. In summary, this thesis revealed the extent of inaccuracy in cuff measured BP compared to intra-arterial BP. Moreover, distinct BP phenotypes were discovered which were related to cuff inaccuracy. Finally, systolic BP amplification was found to influence the accuracy of estimated aortic BP from peripheral BP waveforms. Altogether, these studies substantially advance understanding of the strengths and limitations of current BP measurement methods. Novel reasons for measurement inaccuracy have been identified that may lead to tangible improvements in the accuracy of BP measurement.

In the clinical study, the invasive measurement of the blood pressure can provide signal which is continuous. However, it’s much more inconvenient than the non-invasive one. Due to this reason, this study develops a novel approach and algorithm to measure blood pressure and operate on the smart phone. Using the HD recording function on the smart phone, the wavelength could be detected instantaneously, and the algorithm could be written based on its relationship with blood pressure. In this paper, the approach can be applied to color video recordings of the human face using the HTC smart phone. Post analysis of the video recordings were done using software written in Matlab. The heart rate , systolic and diastolic are derived from the method for measuring multiple physiological parameter. In addition, it is then written into JAVA scripts and transferred into Android phones via the Eclipse program for realistic simulation. It is currently uploaded onto GooglePlay for application download.

Human being’s irregular lifestyles and inappropriate eating habits nowadays result in cardiovascular diseases for citizens at large. The population that is examined having cardiovascular diseases increases every year. Such phenomenon has given blood pressure a lot of attention in the medical field. Blood pressure is an important indicator of a person’s health well being because blood pressure reflects the health status of an individual’s cardiovascular system. This research provides a comprehensive explanation on the methods of measuring blood pressure. The most popular method for blood pressure measuring is by using an electronic sphygmomanometer. Though the electronic sphygmomanometer is advanced enough to adapt a non-invasive measuring method, it still has numerous disadvantages. First, a cuff is required to occlude the blood flow in the arteries during blood pressure measuruing, which causes unpleasant feelings for the users when using. Second, a fixed cuff size may cause measuring errors, which decrease the result accuracy. Last but not least, these devices are bulky and extremely inconvenient to carry around. To remedy the problems that an electronic sphygmomanometer has, this research will illustrate how to use a camera sensor with algorithm to measure the blood pressure. Then such technology is implemented through Android smart phone application. The creation can make an accurate sphygmomanometer available to all citizens who own a smart phone. From that, they can measure their blood pressure wherever they go conveniently and accurately.

Abstract:
The Omron M4 (AS) is an upper arm automatic sphygmomanometer that has not been conclusively validated in clinical trials. The aim of this research was to determine whether the Omron M4 was accurate enough for clinical use. Sixty-two young, apparently healthy participants were recruited. Participants had their blood pressure (BP) taken once with the AS and once with a mercury sphygmomanometer (MS) in random order. Results were compared against the British Hypertension Society (BHS), and the Association for the Advancement of Medical Instrumentation (AAMI) protocols for evaluation of automatic sphygmomanometers. We concluded that the Omron M4 is questionable rating according to previously stated guidelines. This minor thesis was written by a post-graduate student as part of the requirements of the Master of Health Science (Osteopathy) program.

Abstract:
Blood pressure measurements are one part of a circulatory assessment (Docherty and McCallum 2009). Treatments for raised or low blood pressure may be initiated or altered according to blood pressure readings; therefore correct measurement and interpretation of blood pressure is an important nursing skill. Blood pressure should be determined using a standardized technique in order to avoid discrepancies in measurement (Torrance and Serginson 1996). Both manual and automated sphygmomanometers may be used to monitor blood pressure. The manual auscultatory method of taking blood pressure is considered the gold standard (MRHA 2006), as automated monitoring can give false readings (Coe and Houghton 2002), and automated devices produced by different manufacturers may not give consistent figures (MRHA 2006). So, although automated sphygmomanometers are in common use within health care settings in the UK, the skill of taking blood pressure measurement manually is still required by nurses. As a fundamental nursing skill, blood pressure measurement, using manual and automated sphygmomanometers, and interpretation of findings are often assessed via an OSCE. Within this chapter revision of key areas will allow you to prepare thoroughly for your OSCE, in terms of practical skill and understanding of the procedure of taking blood pressure. Blood pressure is defined as the force exerted by blood against the walls of the vessels in which it is contained (Docherty and McCallum 2009). A blood pressure measurement uses two figures—the systolic and diastolic readings. The systolic reading is always the higher figure and represents the maximum pressure of blood against the artery wall during ventricular contraction. The diastolic reading represents the minimum pressure of the blood against the wall of the artery between ventricular contractions (Doughetry and Lister 2008). You will need to be able to accurately identify systolic and diastolic measurements during your OSCE. When a blood pressure cuff is applied to the upper arm and inflated above the level of systolic blood pressure no sounds will be detected when listening to the brachial artery with a stethoscope. The cuff clamps off blood supply. As the cuff is deflated a noise, which is usually a tapping sound, will be heard as the pressure equals the systolic blood pressure —this is the first Korotkoff ’s sound.

Abstract:
Abstract Blood pressure measurement in current medical practice relies on manual methods with the most widely used modality being sphygmomanometers. Utilizing the principle of Photoplethysmography, it is possible to provide an accurate reading of one’s blood pressure through light signals and photodetector devices. This research paper introduces a new Artificial Intelligence driven approach to predict Blood pressure levels and classify them according to the updated ACC (American College of Cardiology) criteria as Normal, Elevated, Stage I, and II Hypertension from the given PPG signal values using Machine Learning Models. This research paper aims to accurately read the Systolic and Diastolic Blood Pressure using Artificial Intelligence, place them into the correct value bins and further prove that the blood pressure values differ based on different skin tones in different light wavelengths such as red, infrared, and green. Machine Learning models such as the Support Vector Machine have shown an accuracy of 70.58% for Systolic Blood Pressure and Decision Tree with an accuracy of 74.4% for Diastolic Blood Pressure classification. The models used in this research are Support Vector Machine, Decision Tree and K-Nearest Neighbor. This research study has future applications and extensions to predict blood pressure levels for patients with different skin tones under different light radiations and PPG signal readings. Neural Network models will be developed to compare the blood predictions from this work.
