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.
