Incremental and Decremental PEEP Titration by Diverse Strategies in Subjects with ARDS: a Prospective Physiological Study

Completed

• Conditions: ARDS

• Registration Number: NCT06808438
• Lead Sponsor: West China Hospital

Brief Summary

The investigators conducted a prospective physiological observation study on ARDS population, described their physiological and EIT indexes with various PEEP titration methods, and also compared and analyzed those indexes to determine whether there were differences among various PEEP titration methods.The objective of this study was to explore and uncover the physiological differences in response to optimal PEEP in different ways，and analyzed the correlation of the optimal PEEP in these different ways.
