WebFeb 18, 2024 · Remote photoplethysmography. PPG imaging (PPGi), or remote PPG (rPPG), is a new PPG technique that involves a video camera with a non-contact feature. Most recent references describe rPPGs. The principle of PR monitoring by rPPG is similar to that of reflectance-mode PPG; however, a two-dimensional (2D) image matrix is used instead … A photoplethysmogram (PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue. A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. A conventional pulse oximeter … See more While pulse oximeters are commonly used medical devices, the PPG derived from them is rarely displayed and is nominally only processed to determine heart rate. PPGs can be obtained from transmissive absorption (as at the … See more Conventional imaging While photoplethysmography commonly requires some form of contact with the human skin (e.g., ear, finger), remote photoplethysmography … See more Monitoring heart rate and cardiac cycle Because the skin is so richly perfused, it is relatively easy to detect the pulsatile component of the … See more • Heart rate monitor • Clitoral photoplethysmograph • Hemodynamics • Laser Doppler imaging See more
