Oxygen is one of the most widely used drugs. It is important to recognise that oxygen administration carries risks as well as benefits. While adequate oxygen saturation of arterial blood is an important factor in tissue oxygen delivery, oxygen administration to patients with chronic obstructive pulmonary disease can lead to decompensated type II respiratory failure. In this debate, Dr Lavery makes the case that high concentration oxygen should be given to all patients treated in an ambulance, while Professor Corris argues against this position.
