Audibility of anaesthesia alarms during magnetic resonance imaging: should we be alarmed?
The effects of MRI acoustic noise on anaesthesia safety concerns have not yet been documented. The objectives of this study were to provide subjective and objective evaluations of anaesthesia alarm audibility during MRI and to review the literature to determine whether or not to worry about our results. ⋯ The audibility of the anaesthesia alarm is significantly reduced during MRI, particularly outside the scanning room. Consequently, optical alarms and interactive screens (outside the room) must be available without exception.
