What “photoplethysmography” means
WikipediaA photoplethysmogram (PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue.

A conventional pulse oximeter monitors the perfusion of blood to the dermis and subcutaneous tissue of the skin.
