A Comparison of Ventilator Parameters (TV, DP, Total Mechanical Power, etc.) Between Successfully and unsuccessfully Weaned Patients with COPD Undergoing Mechanical Ventilation Due to Respiratory Failure, and Diagnosed with Pneumonia or ARDS in the Intensive Care Unit."

The objective of this study is to investigate which mechanical ventilation parameters and clinical findings influence weaning success by comparing successful and unsuccessful weaning patient groups among patients diagnosed with COPD who were intubated and monitored for more than five days in the intensive care unit. The findings of this study may contribute to the development of future treatment protocols and criteria for evaluating the weaning process.

This study is planned to be conducted in two centers: Bakırköy Dr. Sadi Konuk Training and Research Hospital in Istanbul and Shahid Beheshti University of Medical Sciences, Masih Daneshvari Hospital in Tehran. This multicenter study aims to facilitate the comparison of data obtained under different geographical and clinical conditions, thereby enabling a broader analysis of factors influencing the weaning process across a larger patient population.
