Therefore, the the apnea test result is positive (i.e., it supports the diagnosis of brain death). 2 The duration of necessary apnea time to reach a blood level of PaCO 2 of 60 mmHg or an increase of PaCO 2 of 20 mmHg above patient's baseline is variable and depends on factors such as baseline PaCO 2, flow delivery of oxygen, and body temperature. It was first described in 1959, predating widespread organ donation, which has since made its codification critically necessary. The attending physician (or his or her designee) enters the order for the apnea test. This form must be completed and placed into the medical record.

Brain death signifies the complete, irreversible cessation of brain function, including the capacity for the brainstem to regulate respiratory and vegetative activities. This can happen after a severe head injury, bleeding in the brain from a stroke or a haemorrhage, an infection in the brain or a lack of oxygen to the brain.
