Apnoeic oxygenation

Apnoeic oxygenation is used to extend the 'safe apnoea time' beyond that which can be achieved by preoxygenation alone
CCC Critical Care compendium 340


Preoxygenation is the administration of oxygen to a patient prior to intubation to extend 'the safe apnoea time'. The primary mechanism is 'denitrogenation' of the lungs, however maximal preoxygenation is achieved when the alveolar, arterial, tissue, and venous compartments are all filled with oxygen.
