The system outputs a continuous blood pressure waveform
that is similar to a direct arterial pressure waveform
MAP is the accurate driving pressure for analysis of peripheral blood flow13 which does not show any change in the pressure waveform
distally; moreover it is not affected by any distortions or changes that are produced by recording systems.
TUESDAY, June 19, 2018 (HealthDay News) -- A machine-learning algorithm can predict hypotension during surgery based on high-fidelity arterial pressure waveform
analysis, according to a study published online June 11 in Anesthesiology.
The finger photoplethysmography amplitude represents the maximum height of the finger photoplethysmography waveform, and the pulse transit time represents the time it takes for the pulse pressure waveform
to propagate through the arterial tree length.

The above clinical study described the interactions among arterial pressure waveform
, arterial stiffness, and cardiovascular events.
[3-5] In this setting, damping refers to anything which absorbs energy within the oscillating system, resulting in an artificial reduction in the measured amplitude of the oscillating arterial pressure waveform
