심폐소생술 수행자의 엉덩관절 각도가 심폐소생술 결과에 미치는 영향

Effect of Chest Compression Position Depending on the Rescuer’s Hip Joint Angle During Basic CPR

이 연구는 기본심폐소생술 교과목을 이수한 응급구조과 학생을 대상으로 수행자 엉덩관절 각도에 따라 기본심폐소생술의 질이 향상되는지 알아보고자 하였다. 기본심폐소생술 중 엉덩관절 각도에 따른 기본심폐소생술 질(가슴압박 깊이, 완전한 이완, 압박속도 등)을 측정하기 위해 SimPad SkillReporter와 Resusci Anne？？ QCPR？瑛？ 이용하여 비교분석하였고, 2015 AHA Guideline 따랐으며, 가슴압박과 인공호흡의 비율은 30:2로 5주기 시행하였다. 실험군과 대조군의 일반적인 자세에서는 엉덩관절 각도, 인공호흡정도, 가슴압박 깊이, 가슴압박 속도, 가슴압박 이완, 가슴압박정확도, 가슴압박 중단시간(Hands off time), 가슴압박 적용시간 비율은 큰 차이를 보이지 않았다(p > 0.05). 엉덩관절각도를 90도로 유지하는 기본심폐소생술은 유지하지 않았을 때와 큰 차이는 없었으나, 적정깊이와 100% 이완에서는좋은 결과를 보여 주어 보다 더 나은 심폐소생술 질 향상을 기대할 수 있을 것이다.

This study aims to investigate the improvement in basic CPR quality on the basis of the hip joint angle of the rescueramong students in the Department of Emergency Medical Technology who completed a basic CPR curriculum. In this study,we carried out a comparative analysis using SimPad SkillReporter and Resusci Anne？？ QCPR？？ to measure the quality ofCPR (depth of chest compressions, full relaxation, compression speed, and more) on the basis of the rescuer’s hip jointangle in accordance with the 2015 AHA Guidelines and conducted chest compressions and CPR 5 times in a 30:2 ratio. It was found that maintenance of the rescuer’s hip joint angle at 90 degrees while compressing and relaxing the chest madea statistically significant difference in both the experimental and control groups. Moreover, this indicated that the closer thehip joint angle was to 90 degrees, the better was the quality of basic CPR. However, there was no significant differencein the hip joint angle, degree of CPR, depth of chest compressions, chest compression speed, chest compression andrelaxation percentages (%), accuracy of chest compressions, hands-off time during CPR, and percentage of chestcompression time (p > 0.05). Maintaining the hip joint angle at 90 degrees for basic CPR was not significantly differentfrom not maintaining this angle. Nonetheless, good results have been obtained at moderate depth and 100% recoil. Therefore, good outcome and high-quality CPR are expected.
