Comparison of Manual PAOP and Automatic PAOP (Smart Wedge)
Sponsor: Assistance Publique - Hôpitaux de Paris
Summary
The pulmonary artery catheter (Swan-Ganz) is a standard tool in intensive care for measuring and monitoring the pulmonary artery occlusion pressure (PAOP). The Swan-Ganz IQ™ model also allows automatic measurement to reduce the risk of error (Smart Wedge). However, the concordance between this automatic method and the manual method remains poorly studied in real clinical conditions and may vary depending on certain clinical situations. This study therefore aims to compare the PAOP automatically measured (Smart Wedge) with the manual PAOP measurement at bedside based on data collected in clinical practice.

Swan-Ganz IQ™, Smart Wedge
Swan-Ganz IQ™ is a device that provides continuous measurement of cardiac index by analyzing the right ventricular pressure wave. The "Smart Wedge" module provides an automated estimate of PAPO as well as a signal quality indicator ("wedge index"), designed to assess the reliability of the measurement and alert the operator in the event of an unusable signal. This algorithm underwent regulatory validation based on retrospective data compared to an expert interpretation of selected tracings, leading to its approval for clinical use.
