ABSTRACT
OBJECTIVES:
This study was designed to investigate whether an audiovisual feedback (AVF) device is beneficial for quality retention of chest compression (CC) after repetitive practices (RP).METHODS:
After completion of a 45-min CC-only cardiopulmonary resuscitation (CPR) training, participants performed 3 sessions of practices on days 1, 3, and 7 under the guidance of an instructor with (RPâ¯+â¯AVF) or without (RP) the AVF device. CC quality was determined after each session and was retested at 3 and 12â¯months.RESULTS:
In total, ninety-seven third year university students participated in this study. CC quality was improved after 3 sessions in both the RP and RPâ¯+â¯AVF groups. Retests at 3â¯months showed that the proportions of appropriate CC rate and correct hand position were significantly decreased in the RP group as compared with the last practice (pâ¯<â¯0.05). However, no significant changes in CC quality were observed in the RPâ¯+â¯AVF group. However, the proportions of appropriate CC rate, depth, and complete recoil were significantly decreased after 12â¯months in both RP and RPâ¯+â¯AVF groups (pâ¯<â¯0.05). There were no significant differences in these parameters between the RP and the RPâ¯+â¯AVF groups at 12â¯months after RP.CONCLUSION:
With RP, the use of an AVF device further improves initial CC skill acquisition and short-term quality retention. However, long-term quality retention is not statistically different between rescuers who receive verbal human feedback only and those who receive additional AVF device feedback after RP.Palabras clave
