Abstract:

Since its conception decades ago, pulse oximetry-the non-invasive measurement of arterial blood oxygen saturation in real-time-has proven its worth by achieving and maintaining its rank as a compulsory standard of patient monitoring. However, the use of oversimplified models to describe and implement the technology has limited its applicability and has had its evolution at a near standstill for the past decade. Currently available technology relies on empirical calibrations that consist of the correlation between simultaneous measurements from pulse oximeters and invasively acquired arterial b

Abstract:

The goal of this project was to determine the feasibility of non-invasively monitoring the blood gases of construction workers for carbon monoxide exposure via pulse oximetry. In particular, this study sought to understand the impact of motion artifacts caused by the worker's activities and to determine if those activities would prevent the blood gas sensor from detecting the onset of carbon monoxide poisoning. This feasibility study was conducted using a blood oxygen sensor rather than a blood carbon monoxide sensor for several reasons. First, blood gas sensors that measure blood carbon monox

Abstract:

Since the early 1980s the increase in use of pulse oximeters in many clinical situations has been quite remarkable, turning it into one of the most important methods of monitoring in use today. Pulse oximetry essentially uses photoplethysmography to calculate oxygen saturation. Consequently the wavelength dependence of the photoplethysmogram (PPG) is of direct relevance in the performance of pulse oximeters. The experimental results obtained on the wavelength dependence of the AC, DC and AC/DC PPG components for the 450 - 1000nm range are undoubtedly different to the ones predicted by the curr

Pulse oximeters are low-cost, easy to use, and effective at detecting hypoxemia (low blood oxygen levels), a common complication of bronchiolitis, asthma, and pneumonia, the leading infectious cause of death in children worldwide. However, pulse oximeters are often unavailable in lowincome settings, and if available, often underused, yet little research investigates why. In this thesis, I examine pulse oximeter implementation in low-income settings, focusing on Kenyan hospitals as a case study, and using a mixed-methods approach.

Delayed control of haemorrhage or blood loss has been recognised as a major contributor to preventable trauma deaths, but early detection of internal bleeding is difficult due to unreliability of heart rate (HR) and blood pressure (BP) as markers of volume status.

Abstract:

Pulse oximetry is used to measure heart rate (HR) and arterial oxygen saturation (SpO2) from photoplethysmographic (PPG) waveforms. PPG waveforms are highly sensitive to motion artifact (MA), limiting the implementation of pulse oximetry in mobile physiological monitoring using wearable devices. Previous studies have shown that multichannel pulse oximetry can successfully acquire diverse signal information during simple, repetitive motion, thus leading to differences in motion tolerance across channels. In this study, we introduce a multichannel forehead-mounted pulse oximeter and investigate

Abstract:

Pulse oximeters are used in operating rooms and recovery rooms as a monitoring device for oxygen in the respiratory system of the patient. The advantage of pulse oximeters over other methods of oxygen monitoring is that they are easy to use and they are non-invasive, which means it is not necessary break the skin to extract blood for information to be obtained. The standard for the measurement of partial pressure of CO2 and O2 is an arterial blood gas analysis (ABG). However routine monitoring using this method on a continuous basis is impractical since it is slow, painful and invasive. Measur

Abstract:

Recent guidelines recommend oxygen saturation (SpO(2)) levels of 90%-95% for preterm neonates on supplemental oxygen but it is difficult to discern such levels with current pulse oximetry sonifications. We tested (1) whether adding levels of tremolo to a conventional log-linear pulse oximetry sonification would improve identification of SpO(2) ranges, and (2) whether adding a beacon reference tone to conventional pulse oximetry confuses listeners about the direction of change. Participants using the Tremolo (94%) or Beacon (81%) sonifications identified SpO(2) range significantly more accurate

Simultaneous blood perfusion and oxygenation monitoring is crucial for patients undergoing a transplant procedure.

Abstract:

Background: Low-cost, portable fingertip pulse oximeters are widely available to health professionals and the public. They are often not tested to ISO standards, or only undergo accuracy studies in healthy volunteers under ideal laboratory conditions. This study aims to pragmatically evaluate the agreement between one such device and a conventional bedside pulse oximeter in a clinical setting, in patients with varied comorbidities and skin pigmentations. Methods: A single-centre equipment comparison study was conducted. Simultaneous measurements were obtained in 220 patients with both a Contec

Abstract:

Ces dernières années, la supervision continue des signes vitaux des patients a été un sujet d'intérêt de plusieurs travaux de recherche surtout pour ceux qui souffrent de maladies chroniques ou qui travaillent dans des environnements hasardeux. Dans la pratique médicale moderne, le niveau d'oxygène dans le sang est un des signes vitaux primaires tels que la pression artérielle, la fréquence cardiaque, la température corporelle et le rythme respiratoire. L'oxymétrie de pouls est une technique populaire non-intrusive qui permet de diagnostiquer des problèmes liés aux systèmes respiratoire et cir

Abstract:

This thesis presents a novel sigma delta-based pulse oximeter with higher resilience against ambient light interference in comparison to the conventional pulse oximeters available in the market. The pulse oximeter reported in this thesis uses a novel cross-coupled sigma delta modulator to drive the pulse oximeter LEDs with two chaotic, non-overlapping pulse density modulated sequences. The deployment of this modulator not only provides more immunity against ambient light but it also offers more control over the pulse oximeter LEDs power consumption resulting in less power consumption under low

Abstract:

Este estudo tem como objetivo o desenvolvimento de um sistema para oximetria de pulso destinado a medir a saturação arterial de oxigênio. A determinação da saturação de oxigênio no sangue é reconhecida mundialmente como padrão de cuidado em anestesiologia, sendo utilizado em diversas aplicações desde tratamentos intensivos em hospitais até cirurgias veterinárias. O sistema de oximetria desenvolvido emprega um sensor de transmitância utilizando LEDs e um fotodetector como componentes principais. O instrumento é composto de um amplificador de transimpedância, circuito de demultiplexação, filtros

Abstract:

The ability of pulse oximeters to measure carboxyhemoglobin (HbCO) in blood or measure accurate values of oxygen saturation (SpO2) in the presence of elevated levels of HbCO is an important advantage because high exposure to carbon monoxide (CO) can be fatal or results in permanent neurological damage. The aim of my research was to develop an algorithm that would measure SpO2 and SpCO simultaneously using a pulse oximeter. Several specific wavelengths at which changes in SpCO and SpO2 can be measured with high sensitivity and specificity were identified. The choice of these wavelengths was exp

Abstract:

Nos dias de hoje, e estando perante uma sociedade cada vez mais envelhecida e afetada pelo stress e outros fatores de risco tais como obesidade, são evidenciados com maior frequência casos de distúrbios ao nível do sono. Considera-se assim que cerca de dois terços da população apresenta problemas ao nível do sono durante algum momento da sua vida. A dessaturação de oxigénio (SpO2) obtida através de oximetria de pulso noturna é um parâmetro indispensável em medicina do sono, para o diagnóstico de perturbações na respiração durante o sono, principalmente no diagnóstico da Síndrome da Apneia Obst

Abstract:

Існує безліч патологій, які супроводжуються хронічною нестачею кисню в крові (гіпоксією). В цьому випадку показник сатурації кисню крові вимагає постійного спостереження. На сьогоднішній день існує велика кількість пульсоксиметрів, що контролюють вміст кисню в крові та частоту серцевих скорочень (ЧСС).
