ABSTRACT
BACKGROUND:
Bystander cardiopulmonary resuscitation (CPR) is important for survival after cardiac arrest. We hypothesized that elderly laypersons would perform CPR poorer in a realistic cardiac arrest simulation, compared to a traditional test.METHODS:
Sixty-four lay rescuers aged 50-75 were randomized to realistic or traditional test, both with ten minutes of telephone assisted CPR. Realistic simulation started suddenly without warning, leaving the test subject alone in a confined and noisy apartment. Traditional test was conducted in a spacious and calm classroom with a researcher present. CPR performance was recorded with a manikin with human like chest properties. Heart rate and self-reported exhaustion were registered.RESULTS:
CPR quality was not different in the two groups compression depth, 43 mm ± 7 versus 43 ± 4, P = 0.72; compressions rate, 97 min(-1) ± 11 versus 93 ± 15, P = 0.26; ventilation rate, 2.4 min(-1) ± 1.7 versus 2.8 ± 1.1, P = 0.35; and hands-off time 273 s ± 50 versus 270 ± 66, P = 0.82; in realistic (n = 31) and traditional (n = 33) groups, respectively. No fatigue was evident in the repeated measures analysis of variance. Work load was not different between the groups; attained percentage of age predicted maximum heart rate, 73% ± 9 and 76 ± 11, P = 0.37, reported exhaustion 43 ± 21 (scale 0 to 100) and 37 ± 19, P = 0.24.CONCLUSIONS:
Elderly lay people are capable of performing chest compressions with acceptable quality for ten minutes in a realistic cardiac arrest simulation. Ventilation quality and hands-off time were not adequate in either group.
