Medical Gas Cylinder with Mismatched Colour and Pin Index

Abstract

The medical gas cylinders have various safety features to prevent the administration of wrong gas to the patient. Most of the features have visual impact (colour, label, markings on the cylinder body) except pin index system on the cylinder valve, so error in this feature is difficult to analyze and is highly unpredictable. We had received one such cylinder in our institution where all other features (label, colour, marking) pointed to nitrous oxide except the pin index which resembled with that of oxygen
