The purpose of this study is to measure and analyze the number of chest compressions, chest compressions, depth of chest compressions, ventilation, duration of interruption, and accuracy in college students when eyewitness cardiac arrest occurs. The results of the experiment are as follows.(1) The result of the difference in the number of chest compressions was that A was a 20-year-old woman with an average of 114 chest compressions. E was a 22-year-old man with 96 chest compressions, and J was a 24-year-old woman with 109 chest compressions. (2) The result of the difference in chest compressibility depth was that A was a woman in her 20s with an average chest compression depth of 5.0 to 5.2 cm, E was a man in his 20s with an average chest compression depth of 5.0 to 5.4 cm, and J was a woman in her 20s with an average chest compression depth of 5.1 to 5.5 cm. (3) Ventilation was performed for A, E, and J. (4) CPR discontinuation time (second) was performed for a 20-year-old woman for 0 seconds, E was for a 22-year-old man for 5 seconds, and J was a 24-year-old woman for 5 seconds or less. (5) CPR accuracy was found to be 95.2% for a 20-year-old woman, E was found to be a 22-year-old man for 79.6% for a 22-year-old man, and J was found to be 86% for a 24-year-old woman on average. In order to properly cope with an emergency situation in which cardiac arrest occurs, it is confirmed that CPR practice should be sufficiently performed in advance to improve the accuracy of cardiac pressure, and CPR should be performed when cardiac arrest patients occur by maintaining skills through steady retraining.
