What Happened
Hamilton Medical AG initiated a voluntary recall of certain coaxial breathing circuit sets after determining that expiratory valve sets may have membranes sticking to the valve body. This issue is not detectable during pre-operative testing and can trigger an "exhalation obstructed" alarm, potentially resulting in inadequate ventilation and oxygen desaturation.
