A French clinical trial has shown that people getting oxygen on the lower end of the recommended range had a higher 30-day mortality than patients whose partial pressure of arterial oxygen (PaO2) exceeded the recommended target of 55-80 mm Hg.

The trial was halted early because the 90-day death rate was unexpectedly higher among the low-oxygen patients.
