Purpose: This study aimed to compare the effect of chest compression and the resulting ventilation volume in walking cardiopulmonary resuscitation (CPR), straddling CPR, and mechanical CPR while moving manikins to main stretchers. Methods: We compared the chest compressions in terms of compression depth, number of incomplete releases, complete release depth, compression rate, duration between peak time of previous compression and peak time of current compression, and respiration. We analyzed the compression comparatively with the ventilation volume in three different types of CPR. Results: The chest compression depth was significantly improved during straddling CPR as compared to walking CPR, during which women were unable to achieve sufficient chest compression depth. A constant chest compression depth was maintained during mechanical CPR. Conclusion: High-quality chest compressions were difficult to achieve in moving spaces. Further, walking CPR may be helpful in men, but straddling or applying automatic chest compressions in women would result in more effective CPR. Our findings demonstrate the limitations and trends in administering CPR in men and women, which may be useful in devising better education and training methods in the future.

Purpose: The purpose of this study was to evaluate the quality of chest compressions and ventilation when using an mechanical device(LUCAS) and 2-men manual cardiopulmonary resuscitation(CPR) performed on a minikin, as well as to propose a more effective CPR method during transit. Methods: Data were collected by LUCAS and manual virtual reality based ambulance simulation. Analysis was performed using SPSS software 12.0. The average and standard deviation of chest compression depth and ventilation were analyzed using descriptive statistics and t-test. Results: In the virtual reality based LUCAS and manual CPR results, LUCAS showed better chest compression and lower incomplete chest release than manual CPR. During CPR with a chest compression-ventilation ratio of 30:2 in virtual reality ventilation with bag-valve mask was able to deliver an adequate volume of breathing. Conclusion: It is suggested that rescuers on ambulance may consider using LUCAS as an alternative to high-quality chest compression during transit.
