Use of PARniv for Early Diagnosis of LVF in AECOPD

Overview

Left ventricular failure (LVF) is a common cause of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This association is frequently underestimated with regard to the difficulty of clinical diagnosis . The investigators expect that the application of pressure support under NIV could be useful in this issue.

Acute heart failure (AHF) is a common cause of COPD exacerbation however its role is very often underestimated. Until now, the use of echocardiography and some invasive hemodynamic exploration techniques such as the Swan-ganz catheter has been stated as reference. Other noninvasive diagnostic methods have been studied, such as systolic time intervals and Valsalva maneuver, but their application still difficult in patients with COPD exacerbation, especially in emergency department (ED) settings. the study aimed to evaluate the performance of a new diagnostic technique based on the measurement of the PAR using non invasive ventilation (NIV) for the early identification of left ventricular failure (LVF) in patients presenting to the ED with acute COPD exacerbation
