Abstract

Oxygen (O2) is the most commonly used drug in medicine and in anaesthesia.1 It is vital for all aerobic respiration in humans where it acts as the terminal electron acceptor during oxidative phosphorylation, resulting in the synthesis of adenosine triphosphate (ATP). This in turn supplies energy to all the body’s metabolic processes.2
