<br>Pulse oximetry is an important device in patient assessment. Detecting low oxygen levels in patients is important but not at all times easy; central cyanosis - when a patient’s lips, tongue and mucus membranes purchase a blue tinge - might be missed, even by expert observers, till significant hypoxaemia is current.
