Effects of Noise Levels in Cardiopulmonary Resuscitation on Chest Compressions


  • Chung Cheong University, Department of Medical Emergency Technology, Korea, Republic of


This study is investigating the data to increase accuracy and efficiency in performing CPR by comparing chest compression accuracy depending on noise from the surrounding environment. It is an experimental research to test the ability and CPR accuracy of rescuers according to noise based on the same methods and conditions at a place with the noise level of at least 70dB and a place with the noise level below 70dB. In chest compression, the average depth and accuracy was greater in the group with the noise level below 70dB (55.97mm) than the group with the noise level of at least 70dB (54.54mm) (p<.05). Average compression speed (times/min) showed no statistically significant difference with the group with the noise level of at least 70dB at 116.50 times/min, and the group with the noise level below 70dB at 118.46 times/min. Chest compression accuracy (%) was higher in the group with the noise level below 70dB (141.98 times, 94.06%) than the group with the noise level of at least 70dB (132.26 times, 87.41%) (p<.05). The number of chest compression depth error (too weak, times) was greater in the group with the noise level of at least 70dB (13.94 times) than the group with the noise level below 70dB (7.27 times) with statistical significance (p<.05). We think it is necessary to create a calm environment in CPR education and performance, and to actively encourage CPR performance.
