Abstract
Background: Real-time audiovisual feedback devices have been implemented to optimize cardiopulmonary resuscitation (CPR) performance during out-of-hospital cardiac arrest (OHCA). Emergency medical service (EMS) personnel perceive different levels of usability regarding feedback device type. The study aimed to evaluate the effect of type of audiovisual feedback device used during prehospital CPR on chest compression quality during prehospital resuscitation. Method: Adult OHCA patients who received CPR by EMS personnel utilizing feedback device in Seoul between April 2020 and December 2021 were included. Cases that utilized mechanical chest compression devices were excluded. Feedback devices were classified into two types: sticker-type (S-type) and puck-type (P-type). The quality of chest compressions during prehospital resuscitation was compared based on the feedback device type. The primary outcome assessed was chest compression depth. Subgroup analysis was conducted for cases in which EMS personnel had experience using both types of devices. Results: In total, 2,896 OHCA cases were included. 1,596 cases utilized S-type devices and 1,300 cases utilized P-type devices. The median chest compression depth was significantly higher in cases that utilized the S-type device (Median: 5.2, interquartile range (IQR): 4.5-5.8) compared to those that used the P-type device (Median: 4.3, IQR: 3.7-5.0) (P<0.001). In addition, proportion of chest compressions with adequate depth (5-6 cm) was significantly higher in the S-type group, while average chest compression rate and chest compression fraction were higher in the P-type group. Similar findings were observed in the subgroup analysis. Conclusion: Difference in chest compression quality parameters were observed during prehospital resuscitation according to type of audiovisual feedback device utilized. Chest compression quality regarding chest compression depth was superior when S-type feedback device was used.
