There are two issues here that are a matter of concern: first, if delegation of machine checking is to occur, it is imperative that the anaesthetist is fully aware of which checks have been made, so that they can take full responsibility, and second, even if the anaesthetist has a full knowledge of the assistant's checks, but the assistant fails to detect a fault, the responsibility will still lie with the anaesthetist as far as the guidelines are concerned. Healthcare organisations have a responsibility to implement changes in order to reduce healthcare associated infections. Did you use an oxygen analyser?

Steps most commonly omitted were additional monitoring, ventilator function, availability of an alternative means of ventilation and function of ancillary equipment such as laryngoscopes. An anaesthetic machine (British English) ... A two-person pre-use check (consisting of an anaesthesiologist and an assistant) of the anaesthetic machine is recommended before each case and has been shown to decrease the risk of 24-hour severe postoperative morbidity and mortality. Read article Guideline. On the second occasion they followed a visual aid and filled in a questionnaire about the test. It must be emphasised that failure to check the anaesthetic machine and/or the breathing system features as a major contributory factor in many anaesthetic misadventures, including some that have resulted in hypoxic brain damage or death.
