Comparison of Manual PAOP and Automatic PAOP (Smart Wedge)

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.

Inclusion Criteria: * Age ≥18 years; * Admission to an intensive care unit; * Presence of a Swan-Ganz IQ™ pulmonary artery catheter placed as part of patient care; * Measurement of pulmonary artery occlusion pressure (PAOP) performed by the attending clinician as part of patient care. Exclusion Criteria: * Pregnancy; * Court-ordered protective measures. * Refusal to participate by the patient's family members or the patient themselves. * Cardiac output measurements by thermodilution or by continuous cardiac output analysis that cannot be interpreted.
