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

<div>Relationship line normalization. By normalizing the relationship in this way, DPOP may be substituted directly for PPV as a fluid responsiveness parameter. In particular, the same threshold for indication of hypovolemia may be used for both parameters.</div>
