Assessing Cardiac Flow Measurements Using a Noninvasive Photoplethysmography-Based Device Compared to Invasive Pulmonary Artery Catheter.

ABSTRACT:

Background

Invasive monitoring is considered the gold standard for hemodynamic monitoring, yet it poses inherent risks.

Objectives

The aim of the study was to compare invasive hemodynamic measurements using a noninvasive wearable photoplethysmography-based (PPG) monitor and an invasive pulmonary artery catheter.

Methods

Heart failure patients undergoing right heart catheterization were recruited. The PPG-based monitor was applied, and readings of cardiac output (CO) and systemic vascular resistance (SVR) commenced in parallel to invasive hemodynamic measurements and CO calculations using indirect Fick's (IF) and thermodilution (TD) methods. Bland-Altman plots and Pearson correlations were used to assess the accuracy and agreement between the techniques. Limits of agre
