Abstract :

Pulse oximetry is a simple, accurate, universal, non invasive method of measuring arterial oxygen saturation. However, this technique is not devoid of limitations and therefore can show erroneous readings. We herewith discuss an interesting case of false low saturation reading in a patient due to ink smudging of the probe, in a case of emergency LSCS under general anaesthesia.
