Pulse oximetry — physiological considerations [PDF]
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1997 Fetal well-being depends on the level of oxygenation in vital organs such as the heart and brain. In this review, we discuss the physiological parameters which underlie the use of pulse oximetry to evaluate fetal conditions intrapartum. Whilst the measurement of haemoglobin oxygen saturation (SaO2) depends on partial pressure of oxygen (PO2), the ...

Green textile dyeing process by using natural dyes: a review [PDF]
, 2020 In the textile industry, up to 200,000 tons of dyes are lost to effluents every year during the dyeing and finishing operations, due to the inefficiency of the dyeing process. Today, the textile industry used average six hundred dyes and chemical for the

Newborn pulse oximetry screening for critical congenital heart defects
BMC Pediatrics, 2021 We looked at existing recommendations and supporting evidence addressing the effectiveness of pulse oximetry effective for detecting critical congenital heart defects (CCHDs) in newborns. We also looked at the impact of timing of oximetry and the site of

Monte Carlo Analysis of Optical Interactions in Reflectance and Transmittance Finger Photoplethysmography [PDF]
, 2019 Photoplethysmography (PPG) is a non-invasive photometric technique that measures the volume changes in arterial blood. Recent studies have reported limitations in developing and optimising PPG-based sensing technologies due to unavailability of the ...

Ethnic disparities in publicly-available pulse oximetry databases
Communications Medicine, 2022 Sinaki et al. highlight ethnic disparities in the populations of 12 publicly-available pulse oximetry databases. The authors outline the potential consequences of such disparities on pulse oximetry device and algorithm development.
