A “pre-use check” to ensure the correct functioning of anesthetic equipment is essential to patient safety. The anesthesiologist has a primary responsibility of checking the machine and equipment before administration of anesthesia. We report a case where pre-use check would have failed to check delivery of high oxygen had oxygen analyzer not been used. Incorporation of safety features in anesthesia machines and ensuring that a proper check of the machine is performed before use on a patient ensures patient safety.
