Background: The purpose of cardiopulmonary resuscitation (CPR) is for survival of arrest victims. High quality chest compression (CC) is required. We hypothesized the quality of hands-only CPRTM by laypersons may increase with training under real time feeding.
Methods: We recruited prospectively laypersons who were working for one university hospital. Adult volunteers were randomized to receive real-time feedback (with feedback=61), or no feedback (without feedback=49). After training for hands-only CPRTM, CPR performance data was collected with use of CPR recording technology. Quality of CPR was calculated every 30 seconds interval. To identify the quality decay, we used repeated measure analysis of variance with SPSS 19.0 for analysis.
Results: We analyzed quality of CC by 110 subjects. The ratio of correct position compression was higher in feedback group (93.3±19.3 % vs. 88.1±28.0 %, p=0.022). The mean hands-off time was reduced much in feedback group. The ratio of correct depth compression decayed from 60 seconds in Feedback group, from 90 seconds in No-feedback group. The mean compression velocity decayed between 60 to 90 seconds in feedback group.
Conclusions: During hands-only CPRTM, the rate of compression with correct depth may be insufficient. CPR training with use of real-time feedback system may help to compress at appropriate position, and decrease hand-off time.
