Photoplethysmographic Waveform and Pulse Rate Variability Analysis in Hyperbaric Environments

19 Apr, 2021

Morphological changes in pulse rate could provide complementary information to that extracted from the pulse rate variability on the response of the cardiovascular and nervous systems of subjects exposed to hyperbaric environments. The peripheral activation produces a vasoconstriction that increases the pulse width and area. However, the pulse width of the anacrotic phase seems to be a better marker in the variation of peripheral vascular resistance than the pulse width.
