Increased central systolic loading may contribute to ischaemic symptoms in cardiac syndrome X (CSX). Resting and exercise-induced central pressure waveforms were recorded in 20 CSX patients and 20 ...
Over the last decade a number of studies have been reported that have used heart–lung interactions during mechanical ventilation to assess fluid responsiveness. Specifically, the pulse pressure ...
We report the case study of a 68-year-old female with cardiac syndrome X presenting with abnormal pressure waveforms and a hypertensive response to exercise with ST-segment depression. After ...
Manufacturers increasingly but still infrequently follow Food and Drug Administration guidance that recommends testing pulse oximeters on participants with a range of skin pigmentations, according to ...

Dr. Takuo Aoyagi, a Japanese bioengineer, was the first to invent pulse oximetry in 1974. 2 The pulse oximeter is based on the light absorption characteristics of hemoglobin at different wavelengths.
Please provide your email address to receive an email when new articles are posted on . Pulse oximeter inaccuracy due to darker skin tones was found in 30 out of 44 studies. Some studies showed a ...
Normal blood oxygen level is either 95%-100% SpO2 on an oximeter or 80-100 mm Hg from an ABG test. ABG tests are more accurate than pulse oximeters, which have a ...
