BACKGROUND: Multiple factors may contribute to the observed survival variability following in-hospital cardiopulmonary resuscitation (CPR). While in-hospital CPR is most often performed on patients lying on a bed or stretcher, CPR training uses primarily manikins placed on the floor. We analyzed the quality of external chest compressions (ECC) in simulated cardiac arrest scenarios occurring both on a stretcher and on the floor. METHODS: Prospective cross-over simulation study enrolling ED nurses and nurse's aides as part of an annual evaluation. Simulated CPR was performed in the 2 rescuer-mode for 2 min, both kneeling on the floor, and standing beside a knee high stretcher. The order of position was randomized. ECC parameters were compared. RESULTS: ED nurses (n=48) and nurse's aides (n=26) performed 128 scenarios. Mean ECC depth was 32±13 mm on the floor and 27±11 mm on a stretcher (?: 5 mm, 95%CI [3-7], P<.001). Participants last trained within a year (n=17) developed deeper ECCs than their colleagues (n=47) in both positions (floor: 39±12 mm vs stretcher: 34±11 mm (p=0.016) for those trained within the year, and floor: 29±12 mm vs stretcher: 24±10 mm (P<.001) for those trained over a year ago). CONCLUSIONS: The quality of chest compressions performed by ED staff was below 2005 guideline standards, with decreased ECC depth during CPR on a stretcher. Annual refresher courses should be implemented in the ED, with a focus on obtaining required ECC depth while standing next to a stretcher.
