This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tested whether having conscious COVID-19 patients with breathing problems lie face down (prone position) while on high-flow oxygen could reduce the need for a breathing tube. Over 400 adults with COVID-19 pneumonia and mild to severe acute respiratory distress syndrome took part. The goal was to see if this simple positioning technique could improve outcomes and ease pressure on intensive care units.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
prone positioning
What this could lead to
If it works, this simple technique could reduce the need for intubation and free up critical care resources during COVID-19 surges.
What could go wrong
This is a completed trial, but results may not apply to all patients or future variants. The intervention is supportive, not a cure, and some patients may still require intubation.
