The Relationship between Body Composition and Chest Compression in Adult -A Manikin Study-

This study analyzed the correlation between chest compression results and body composition over time in cardiac arrest patients.The experiment was conducted by 16 second grade students of the emergency rescue department who completed the CPR course. All the date were analyzed using the SPSS software 20.0(SPSS Inc., Chicago, IL, USA).The ability to maintain effective chest compressions declined rapidly over time, and in the female group, it was confirmed that it decreased significantly after 1 minute. For factors influencing the depth of compression, the higher the back-muscle strength, the better the compression depth was maintained. Also the lower the body fat percentage, the more effective chest compression was maintained.If the Cardiopulmonary resuscitation(CPR) is performed for more than 10 minutes, it seems desirable that more than 3 people take turns for chest compressions rather than 2 people.
