PRONE POSITIONING: From basic concepts to practice

This article was first written during the outbreak of the SARS-CoV-2 pandemic, even though at the time the contagion is decreasing, I still think it’s very important to offer a small summary of the theory and techniques used during the process of prone positioning in patients affected with ARDS (Acute Respiratory Distress Syndrome). The prone position involves positioning the patient ventral side down and dorsal side up.

The main question is: why do we prone position patients that are affected by ARDS?

In order to understand this asynchrony, it is important to know the meaning of ” Entraiment”. In physics, this term defines the phase and the timeline of a periodic external output. In a neuroscientific field, “entrainment” is when the cerebral waves show a superimposable oscillation on a periodic external stimulus. For example, exposure to music can cause a “respiratory entrainment” in the respiratory area of expertise attributed to a permanent and repetitive reaction between neural respiratory cycles distributed by the ventilator.
