    BackgroundDispatcher assisted cardiopulmonary resuscitation (DA-CPR) increase the rate of bystander CPR. The aim of the study was to compare the performance of DA-CPR and attainable skills following CPR training between young and elderly laypersons.MethodsVolunteer laypersons (young: 18-40 years; elderly: > 65 years) participated. Single rescuer CPR was performed in a simulated DA-CPR cardiac arrest scenario and after CPR training. Data were obtained from a manikin and from video recordings. The primary endpoint was chest compression depth.ResultsOverall, 56 young (median age: 26, years since last CPR training: 6) and 58 elderly (median age: 72, years since last CPR training: 26.5) participated. Young laypersons performed deeper (mean (SD): 56 (14) mm vs. 39 (19) mm, P < 0.001) and faster (median (25th-75th percentile): 107 (97-112) per min vs. 84 (74-107) per min, P < 0.001) chest compressions compared to elderly. Young laypersons had shorter time to first compression (mean (SD): 71 (11) seconds vs. 104 (38) seconds, P < 0.001) and less hands-off time (median (25th-75th percentile): 0 (0-1) seconds vs. 5 (2-10) seconds, P < 0.001) than elderly. After CPR training chest compressions were performed with a depth (mean (SD): 64 (8) mm vs. 50 (14) mm, P < 0.001) and rate (mean (SD): 111 (11) per min vs. 93 (18) per min, P < 0.001) for young and elderly laypersons respectively.ConclusionDespite long CPR retention time for both groups, elderly laypersons had longer retention time, and performed inadequate DA-CPR compared to young laypersons. Following CPR training the attainable CPR level was of acceptable quality for both young and elderly laypersons.© 2017 The Acta Anaesthesiologica Scandinavica Foundation.
