Effect of Initial Empirical Positive End-Expiratory Pressure (PEEP) Setting on the Esophageal Pressure-guided PEEP Titration in Acute Respiratory Distress Syndrome
Effect of Initial Empirical Positive End-Expiratory Pressure (PEEP) Setting on the Esophageal Pressure-guided PEEP Titration in Acute Respiratory Distress Syndrome
Esophageal manometry was used as surrogate of pleural pressure to titrate positive end-expiratory pressure (PEEP) in ARDS patients. However, Absolute values of esophageal pressure (Pes) could be affected by the PEEP setting. In moderate to severe ARDS patients, the end-expiratory Pes changed differently with PEEP adjustment. and the esophageal phenotypes could be divided into type I and type II. with Type I （ΔPes≥30%ΔPEEP）and Type II（ΔPes<30%ΔPEEP）.
Inclusion Criteria:
- aged over 18 all the moderate to severe ARDS patients invasive mechanical ventilation
