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 ...
Penile plethysmography (PPG) or phallometry is a measurement of blood flow to the penis, typically used as a proxy for measurement of sexual arousal.The most commonly reported methods of conducting penile plethysmography involves the measurement of the circumference of the penis with a mercury-in-rubber or electromechanical strain gauge, or the volume of the penis with an airtight cylinder and ...

Photolabile protecting group. A photolabile protecting group ( PPG; also known as: photoremovable, photosensitive, or photocleavable protecting group) is a chemical modification to a molecule that can be removed with light. PPGs enable high degrees of chemoselectivity as they allow researchers to control spatial, temporal and concentration ...
Photoplethysmogram variability. The photoplethysmogram (PPG) measurement made at a peripheral site, such as the finger, ear or forehead represents the volume of blood in the vessel at the site of measurement. The PPG signal consists of pulses that reflect the change in vascular blood volume with each cardiac beat. Beat-to-beat fluctuations ...
