Physiological effects of awake prone position in acute hypoxemic respiratory failure.

ABSTRACT:

Background

The effects of awake prone position on the breathing pattern of hypoxemic patients need to be better understood. We conducted a crossover trial to assess the physiological effects of awake prone position in patients with acute hypoxemic respiratory failure.

Methods

Fifteen patients with acute hypoxemic respiratory failure and PaO₂/FiO₂ < 200 mmHg underwent high-flow nasal oxygen for 1 h in supine position and 2 h in prone position, followed by a final 1-h supine phase. At the end of each study phase, the following parameters were measured: arterial blood gases, inspiratory effort (ΔP_ES), transpulmonary driving pressure (ΔP_L), respiratory rate and esophageal pressure simplified pressure-time product per minute (sPTP_E
