On Better Estimating and Normalizing the Relationship between Clinical Parameters: Comparing Respiratory Modulations in the Photoplethysmogram and Blood Pressure Signal (DPOP versus PPV)

<div>Deriving DPOP from the pleth. The amplitude of the cardiac component of the pleth waveform modulates due to respiratory-related changes in intrathoracic pressure which alters cardiac function. Principally, this stems from decreased left ventricular stroke volume during inspiration, leading to decreased pulse amplitude during this phase of respiration.</div>
