Studies of mask fit testing appear to lack the reporting of outcomes for each manoeuvre with only the cumulative results being provided. This finding raises the need to understand potential risk from a mask leak during the delivery of clinical care as evidenced by failing a manoeuvre during mask fit testing. Further research …
