Photo Plethysmogram, BSL
Part #: SS4LA

The SS4LA photoplethysmogram (PPG) transducer operates with the data acquisition unit to record the blood volume pulse waveform via optical methods.

The SS4LA consists of a matched infrared emitter and photo diode detector, which transmits changes in infrared reflectance resulting from varying blood flow. Blood is highly reflective of near infrared light wavelengths, due to the heme subunit of hemoglobin. When the PPG transducer is placed on the skin, in proximity to capillaries, the reflectance of the infrared light from the emitter to the detector will change in accordance to capillary blood volume. The PPG waveform peaks when capillary blood volume is maximized.
