Management of simulated oxygen supply failure: is there a gap in the curriculum?

In this study we evaluated, in our residency program, the understanding and management of a simulated oxygen pipeline failure. Performances of 20 residents were evaluated by 2 raters. Fourth-year residents did not perform better than second-year residents (P = NS). The majority of the participants either did not have the knowledge to change the oxygen cylinder or did not attempt to change the oxygen, even after prompting. We conclude that the delegation of gas machine maintenance to perioperative personnel, such as respiratory therapists and technicians, may have created a new gap in knowledge and resulted in inadequate training.
