Photoplethysmography is a non-invasive method which is suitable to estimate vascular compliance. Photoplethysmogram (PPG) waveform has been used to evaluate vascular characteristic changes due to exercise. Quantification of the primary and secondary peak position is of interest as a potential objective, individualized measure of the level of exercise that a subject has achieved with respect to a baseline...
Photoplethysmography can be used to estimate vascular compliance and arterial blood oxygen saturation. To ensure accurate measurement in the various applications, it is of interest to study the changes in the photoplethysmogram (PPG) waveform under different conditions. Ten people participated in the study to analyze the changes in the width ratio of the PPG waveform immediately and 20 minutes after...
Pulse contour analysis was used to determine systemic arterial vascular compliance in hypertensive (HT) and normotensive (NT) subjects. In seven hypertensives aged 43-58 yrs (mean age 52.1+or-5.5 yrs) and seven normotensives aged 33-59 yrs (mean age 43.7+or-9.9 yrs) both large artery (C1) and distal arterial (C2) compliance were determined from a peripheral arterial pressure waveform and cardiac output...
