Measure variations in blood flow indirectly via changes in opacity with the plethysmogram transducer for tethered, wireless and MRI applications.
Typically, a blood volume pulse (BVP) transducer—otherwise known as a pulseplethysmogram or photoplethysmogram (PPG) transducer—is attached to the finger or toe to record the peripheral pulse. AcqKnowledge® will calculate measurements on a beat-by-beat basis.
PPG (Pulse Plethysmogram) and BVP (Blood Volume Pulse) are two names for very similar measurements. BVP is the signal that results when highpass filtering the PPG signal. The choice of highpass filter is a bit arbitrary, but typically it is a value between 0.05 Hz and 0.5 Hz.
The situation is very similar to EDA. In this case there is tonic EDA which is the entire EDA signal. And the highpass filtered version of tonic EDA is phasic EDA which isolates the specific delta responses at a certain point in time. BVP is metaphorically equivalent to phasic EDA. PPG is similarly equivalent to tonic EDA.
Changes in the PPG baseline are indicative of the overall amount of blood in the capillary bed.
Please note that the VPG (Vaginal Photoplethysmogram) is identical to the PPG but designed to measure capillary blood flow/presence in the vaginal wall.
