title: Should we pre-oxygenate?
abstract: The importance of routine pre-oxygenation before induction of anaesthesia was demonstrated in animals. The onset of dangerous levels of hypoxia after the administered of suxamethonium can be delayed considerably by the administration of pure oxygen for 5 minutes before induction. This allows time for an atraumatic and a panic-free intubation before controlled ventilation. After pre-oxygenation the volume of oxygen in the functional residual capacity of the lungs shows a sixfold increase. This is the principal oxygen store during apnoea.
