During the prone position, there may be an increase in intragastric pressure. The investigators focus on a scientific question: Whether reducing enteral nutrition before the prone position will benefit patients with severe mechanically ventilated acute respiratory distress syndrome (ARDS).
The experimental group had the enteral nutrition dose reduced before the prone position, while the control group did not have the enteral nutrition dose reduced
