WebbWhat is Photo-Plethysmography? Photo-plethysmography (PPG) sensors are vital in every physiological vascular testing examination. The PPG sensors transmit infra-red waveforms to the skin and detect the signals that are reflected back to the sensor from the skin.

Adjustable according to the size of the animal 3 sizes lenght:130,160 et 190 mm. Ø 60 mm. 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 finger tip) or reflection (as on the forehead). In outpatient settings, pulse oximeters are commonly worn on the finger. However, in cases of shock, hypothermia, etc., blood flow to the periphery can be reduced, resulting in a PPG without …
