Prone positioning improves ventilation-perfusion matching assessed by electrical impedance tomography in patients with ARDS: a prospective physiological study.

ABSTRACT:

Background

The physiological effects of prone ventilation in ARDS patients have been discussed for a long time but have not been fully elucidated. Electrical impedance tomography (EIT) has emerged as a tool for bedside monitoring of pulmonary ventilation and perfusion, allowing the opportunity to obtain data. This study aimed to investigate the effect of prone positioning (PP) on ventilation-perfusion matching by contrast-enhanced EIT in patients with ARDS.

Design

Monocenter prospective physiologic study.

Setting

University medical ICU.

Patients

Ten mechanically ventilated ARDS patients who underwent PP.

Interventions

We performed EIT evaluation at the initiation of PP, 3 h after PP initiation and the end of PP during the first PP session.
