Critically ill patients are often transported by air ambulances. Although these patients are likely to require cardiopulmonary resuscitation (CPR) during transport, the effects of the air medical transport environment on CPR efficacy have never been studied. ⋯ Chest c compressions performed in the BK-117 helicopter were as effective as those performed in the control environment, but compressions performed in the BO-105 were significantly less effective than controls. In conclusion, in a manikin model, chest compressions are substandard in the BO-105 helicopter because of the limited space available in the aircraft.
