Abstract
Objective: This randomized crossover simulation study aimed to compare the effectiveness of chest compressions, performed during 10 minutes of cardiopulmonary resuscitation, in three different compression postures: standing posture (SP), single-leg kneeling posture (SLKP) and both legs kneeling posture (BLKP) on a manikin lying on a bed.
Method: Enrolled participants were doctors, nurses and emergency medical technicians who worked in the emergency department and performed chest compressions (CCs) without ventilation for 5 sessions (10 minutes) in the three compression postures from June to August 2019. The chest compression parameters (CCPs) such as compression depth, compression rate (CR), the accuracy of compression depth (ACD) and accuracy of relaxation (AR) were collected by the Resusci Anne PC skill report system. The statistical differences of CCPs between three postures were analyzed.
Results: A total of 32 participants were enrolled in this study. There were no significant differences between SP, SLKP and BLKP on compression depth (52.6 vs. 53.2 vs. 50.9 mm, P>0.05), CR (110.2 vs. 111.8 vs. 111.6 compressions/min, P>0.05), ACD (43.7% vs. 47.0% vs. 46.3%, P>0.05), and AR (99.4% vs. 99.0% vs. 99.3%, P>0.05). There were no significant differences in CCPs according to chest compression time in the three postures. However, there was a significant difference between the SP and BLKP (16.0 vs. 14.0, P=0.023) on the Borg scale of subjective fatigability.
Conclusion: In our study, when rescuers performed chest compression on a hospital bed, the parameters of CCs for the three compression postures were similar.
