title: Prevention of accidents associated with air-oxygen mixers.
abstract: Some time ago three patients were threatened by severe hypoxia. They did not demonstrate any adverse late effects, though the situation could as well have brought a fatal outcome. The incidents were related to the use of an oxygen-air mixing device. As this apparatus is widely used it is worthy of comment regarding its potential danger.
