Brief pre-oxygenation may avert hypoxaemia in low-risk mask induction; leaves open optimal protocols and generalizability.
Does pre-oxygenation prevent hypoxaemia during induction of mask anaesthesia in ASA 1 patients?
A minimum of a few breaths of pre-oxygenation is necessary to avoid hypoxaemia during induction of mask anaesthesia.
Thorpe et al. (1990) studied this question.
