A photoplethysmogram ( PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue. [1] [2] A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. [3] A conventional pulse oximeter monitors the perfusion of blood to ...
Polypropylene glycol or polypropylene oxide is the polymer (or macromolecule) of propylene glycol. [1] Chemically it is a polyether, and, more generally speaking, it's a polyalkylene glycol (PAG) H S Code 3907.2000. The term polypropylene glycol or PPG is reserved for polymer of low- to medium-range molar mass when the nature of the end-group ...
