Summary

Oxygenation is the primary aim of all airway management. The shape of the oxyhaemoglobin dissociation curve determines onset of hypoxaemia and means that when it occurs it can progress rapidly and severely. Hypoxaemia causes rapid damage to living tissues, most importantly the brain. Oxygenation strategies are required including delivering oxygen before, during and after airway management. Low flow oxygenation techniques are traditionally employed and apnoeic oxygenation has been rarely used. Newer high flow oxygen delivery systems enable effective pre-oxygenation and apnoeic oxygenation and can be used both during complex airway management or as an alternative to instrumenting the airway during surgery.
