Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to investigate the effects of EIT-guided and Pplat-guided Phigh settings on regional ventilation and perfusion in ARDS patients during APRV, while also examining the impact of different Phigh settings on gas exchange, respiratory mechanics, and hemodynamics.

Intervention group

EIT-guided Phigh settings during APRV

Group Type EXPERIMENTAL

EIT-guided Phigh settings during APRV

Intervention Type DEVICE

The Phigh level selected for the patients in the Intervention group was the intercept point of cumulated collapse and overdistension percentage curves, providing the best compromise between collapsed and overdistended lung.

Control group

Pplat-guided Phigh settings during APRV
