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.

Abstract:

Accurately measuring blood pressure (BP) is essential for maintaining physiological health, which is commonly achieved using cuff-based sphygmomanometers. Several attempts have been made to develop cuffless sphygmomanometers. To increase their accuracy and long-term variability, machine learning methods can be applied for analyzing photoplethysmogram (PPG) signals. Here, we propose a method to estimate the BP during exercise using a cuffless device. The BP estimation process involved preprocessing signals, feature extraction, and machine learning techniques. To ensure the reliability of the signals extracted from the PPG, we employed the skewness signal quality index and the RReliefF algorithm for signal selection. Thereafter, the BP was estimated using the long short-term memory (LSTM)-based neural network. Seventeen young adult males participated in the experiments, undergoing a structured protocol composed of rest, exercise, and recovery for 20 min. Compared to the BP measured using a non-invasive voltage clamp-type continuous sphygmomanometer, that estimated by the proposed method exhibited a mean error of 0.32 ± 7.76 mmHg, which is equivalent to the accuracy of a cuff-based sphygmomanometer per regulatory standards. By enhancing patient comfort and improving healthcare outcomes, the proposed approach can revolutionize BP monitoring in various settings, including clinical, home, and sports environments.

Abstract:

A sphygmomanometer is a standard testing tool for monitoring blood pressure and plays a vital role in modern medical diagnosis. Traditional smart electronic sphygmomanometers are complex and costly; this paper designs a low-cost electronic pulse sphygmomanometer through microcontroller control. This design collects the gas pressure information through the barometric pressure sensor and inputs it into the analog-to-digital converter. It converts the collected analog signal into a digital signal and then completes the determination of blood pressure and pulse through the recognition algorithm. Finally, this design is found to have the advantages oa f wide range of applicationslightweightht, low price, etc., and has important application value.

Abstract:

Background: This study aimed to collect data to compare blood pressure values between random-zero sphygmomanometers and automated oscillometric devices and generate equations to convert blood pressure values from one device to the other. Methods: Omron HEM-907, a widely used automated oscillometric device in many epidemiologic surveys and cohort studies, was compared here with random-zero sphygmomanometers. In total, 201 participants aged 40-79 years (37% men) were enrolled and randomly assigned to one of two groups, with blood pressure measurement first taken by automated oscillometric devices or by random-zero sphygmomanometers. The study design enabled comparisons of blood pressure values between random-zero sphygmomanometers and two modes of this automated oscillometric device (automated and manual), and assessment of effects of measurement order on blood pressure values. Results: Among all participants, mean blood pressure levels were the lowest when measured with random-zero sphygmomanometers compared with both modes of automated oscillometric devices. Several variables, including age and gender, were found to contribute to the blood pressure differences between random-zero sphygmomanometers and automated oscillometric devices. Equations were developed using multiple linear regression after taking those variables into account to convert blood pressure values by random-zero sphygmomanometers to automated oscillometric devices. Conclusions: Equations developed in this study could be used to compare blood pressure values between epidemiologic and clinical studies or identify shift of blood pressure distribution over time using different devices for blood pressure measurements.

Abstract:

Background: Outbreaks of healthcare-acquired infections have been linked to contaminated medical devices such as electronic thermometers, sphygmomanometers, stethoscopes, latex gloves, masks, neckties, white coats and other. Objective: The aim of this study was to assess non-critical healthcare tools as a potential source of healthcare-acquired bacterial infections and associated factors in public health hospitals of Harar, eastern Ethiopia from March 2016 to February 2017. Methods: A hospital-based cross-sectional study was conducted on 212 non-critical healthcare tools owned by different health professionals. The data were collected from each owner using self-administered questionnaire. Swab specimens were collected from 187 stethoscopes and 25 sphygmomanometers using sterile cotton tips. Bacterial investigation and antimicrobial susceptibility tests were performed using standard culture tests. The data were double entered into EPI-Data version 3.1 and exported into the Statistical Package for Social Sciences version 16 for analysis. Result: The overall prevalence of non-critical healthcare tool contamination was 53.8%. A total of 137 bacterial strains were isolated. Staphylococcus aureus was the most frequent isolate (35%). Resistance to two or more different classes of antimicrobial was found to be 19.3%. The proportion of stethoscopes or sphygmomanometers contamination owned by the health professionals who were not cleaned regularly before and after examining each patient was found to be high (77%). The majority of non-critical healthcare tools used by health professionals working in the intensive care unit were contaminated (75%) followed by medical wards (73.5%). Conclusion: This study confirmed that the majority of the stethoscopes and sphygmomanometers were contaminated with pathogenic bacteria known to be associated with healthcare-acquired infections. Most of the healthcare workers did not practice stethoscope and sphygmomanometers disinfection. Strict and careful decontamination of stethoscopes and sphygmomanometers need to be in place before use.

Abstract:

Background: Atrial fibrillation (AF) has affected millions of adults in the world. It is important to monitor and manage blood pressure (BP) in AF patients. The accuracy of BP monitoring in AF patients with noninvasive methods remains questionable, however. Objectives: To compare the accuracy of different noninvasive BP devices (oscillographic sphygmomanometer and pulse wave device) for BP measurement in elderly patients with AF, with a mercury sphygmomanometer as a reference. Design: This study was an observational study. Methods: Patients with AF from the inpatient department of cardiology were included from 1 January to 31 December 2020. BP measurements were performed by two trained nurses using a tee junction connection on the cuff to connect three sphygmomanometers. The Bland–Altman plot analysis was conducted to compare the agreement of BP measurements. We also compared the agreement of BP measurements through metrics such as accuracy, bias, and precision. Results: A total of 202 patients (54.5% female) were included. The Bland–Altman plot analysis showed that the lower and upper limits of agreement (LoAs) of pulse wave/reference were similar to the predefined acceptable clinical limits (10/5 mmHg). The bias and precision in both systolic and diastolic BP were significantly less in pulse wave/reference (a bias of 1.8 and 0.77 mmHg and a precision of 5.20 and 4.66 mmHg, respectively), with corresponding higher accuracy readings (98.51% for P10 in systolic BP and 85.64% for P5 in diastolic BP). Conclusion: A novel noninvasive sphygmomanometer – pulse wave device has a good concordance with a mercury sphygmomanometer in BP monitoring, and may be applicable to perform BP measurements in the elderly with AF.

Abstract:

Background: Sphygmomanometers and their cuffs are non-critical items that can act as a fomite for transmission of pathogens which may cause healthcare-associated infection (HAI), leading to an argument that disposable equipment improves patient safety. Aim: The aim of this study was to demonstrate that decontamination decreased in microbial contamination of non-disposable sphygmomanometer cuffs, providing evidence to negate the need to purchase, and dispose of, single-patient-use cuffs, reducing cost and environmental impact. Methods: A pre–post intervention study of available sphygmomanometer cuffs and associated bedside patient monitors was conducted using a series of microbiological samples in a rural emergency department. A Wilcoxon signed-rank test analysed the effect of the decontamination intervention. To further examine the effect of the decontamination intervention, Mann–Whitney U-tests were conducted for each aspect. Findings: Contamination was significantly higher before decontamination than afterwards (Z = −5.14, U = 55.0, P < 0.001, η2 = 0.61 inner; Z = −5.05, U = 53.5, P < 0.001, η2 = 0.59 outer). Discussion: Decontamination of non-disposable sphygmomanometer cuffs decreases microbial load and risk of HAI, providing evidence to negate arguments for disposable cuffs while being environmentally sensitive and supportive of a culture of patient safety and infection control.

Abstract:

A manual sphygmomanometer is an instrument used to measure blood pressure, and consists of an inflatable cuff, a mercury manometer (or aneroid gauge) and an inflation ball and gauge. To assess the condition, accuracy and safety of mercury and anaeroid sphygmomanometers in use in general practice and to pilot a scheme for sphyg- momanometer maintenance within the district. Therefore, it must be calibrated periodically. Using the MPX 5050GP sensor as a positive pressure sensor. Requires a maximum pressure of 300 mmHg. This tool is also equipped with a SD Card as external storage. The display used in this module is TFT Nextion 2.8”. After conductings measurements of the three comparisons consisting of Multifunction, DPM and mercury tensimeter to 6 times, the smallest result 0 mmHg and the largest results 251.52 mmHg. While the error in mercury tensimeter’s of leak test to module and rigel is 0.56% and 0.404%.

Abstract:

Appropriate calculation and use of reference intervals have widespread clinical and research implications. Unfortunately, reference intervals for blood pressure in one of the most commonly used NHP species, rhesus macaques (Macaca mulatta), have never been calculated. Although anesthetic drugs and noninvasive methods of blood pressure measurement both have known effects on blood pressure values, their use provides the safest, fastest, and most widely used approach to clinical evaluation and blood pressure collection in this species. We analyzed noninvasive blood pressure measurements from 103 healthy, ketamine-sedated, adult (age, 8 to 16 y) rhesus macaques, representing both sexes, with various body condition scores by using 2 types of sphygmomanometers at 3 different anatomic locations. Reference intervals were calculated for each device, in each location, thus establishing normative data beneficial to clinical veterinarians assessing animal health and encouraging researchers to use noninvasive methods. Age, body condition score, sex, type of sphygmomanometer, and location of cuff placement were all found to influence blood pressure measurements significantly, providing important information necessary for the appropriate interpretation of noninvasive blood pressure values in rhesus macaques.
