The aim of this randomized, cross-over trial is to reveal the effect of smartphone cardio-pulmonary resuscitation (CPR) feedback applications (App) on a group of lay rescuers' chest compression-only CPR quality metrics. Quality metrics is measured initially and after 3 months.
A floor-based Resusci Anne mannequin (Laerdal Medical, Stavanger, Norway) was used. Three scenarios (CPR with device App-on [scenario-a], CPR with device App-off [scenario-b], and hands-only CPR [scenario-c]) were randomly allocated to all participants. All the participants performed 2 min of hands only-CPR for each scenario. Data of mean chest compression rate, mean chest compression depth, and recoil were recorded and compared for each scenario.
One hundred and thirty-seven first-year students from the Vocational School of Health Services in Turkey participated in this study to mimic lay rescuers. Difference in the initial mean rate of chest compressions was statistically significant when CPR was performed with device App-on (scenario-a) compared to scenarios b and c ( < 0.001, < 0.001). Furthermore, difference in the mean chest compression rate at the 3 month was statistically significant among the scenarios when CPR was performed with device App-on (scenario-a) ( = 0.002, = 0.001). The difference in initial and 3 month mean compression depth and the percentage of recoil was not statistically significant among the scenarios.
This study shows that the mean chest compression rate and percentage of compressions with adequate rate improved with smartphone App-on, and these results were persistent up to 3 months.
本随机交叉试验旨在揭示智能手机心肺复苏（CPR）反馈应用程序（应用）对一组非专业救援人员仅进行胸外按压的心肺复苏质量指标的影响。在初始阶段和3个月后测量质量指标。
使用基于地面的复苏安妮模拟人（挪威斯塔万格Laerdal Medical公司）。将三种场景（使用设备且应用程序开启的心肺复苏[场景a]、使用设备且应用程序关闭的心肺复苏[场景b]和仅进行双手按压的心肺复苏[场景c]）随机分配给所有参与者。所有参与者针对每种场景进行2分钟的仅双手按压心肺复苏。记录并比较每种场景下的平均胸外按压速率、平均胸外按压深度和回弹数据。
来自土耳其卫生服务职业学校的137名一年级学生参与本研究以模拟非专业救援人员。与场景b和c相比，使用设备且应用程序开启（场景a）进行心肺复苏时，初始平均胸外按压速率的差异具有统计学意义（<0.001, <0.001）。此外，使用设备且应用程序开启（场景a）进行心肺复苏时，3个月时平均胸外按压速率在各场景之间的差异具有统计学意义（=0.002, =0.001）。各场景之间初始和3个月时的平均按压深度以及回弹百分比的差异无统计学意义。
本研究表明，使用智能手机应用程序开启时，平均胸外按压速率和足够速率的按压百分比有所提高，且这些结果持续至3个月。
