Hypoxaemia during apnoeic oxygenation complicates tests for brainstem death and exposes the patient's organs to the risk of anoxic damage. This study investigates the effect on hypoxaemia of varying the ambient oxygen fraction during apnoea.
Methods and results
Provision of very high ambient oxygen fractions greatly extends the safe duration of apnoea. As oxygen fraction is increased, increasingly large effects are achieved.
