Abstract

The purpose of this study was to demonstrate the effect on the degree of fatigue and accuracy of cardiopulmonary resuscitation according to the different time delays (3 minutes, 4 minutes). Carrying out repeated measures of variance (repeated ANOVA), we have shown that time effect (F = 7.835, p <.01) and group effect (F = 8.695, p<.01) and the interaction effect between time and group (F = 12.582, p<.001) were all statistically significant. It means, in the test of the main effect of group and time (3 minutes, 4 minutes) using the Bonferroni method, it turned out that the amount of lactic acid of the experimental group was larger than that of the control group (p<.01), and there was no difference until 3 minutes, but the difference of the amount of lactic acid was shown between before the experiment and after 4 minutes, and between 3 minutes and 4 minutes (p <.05), respectively. Then, in the result of the corresponding sample t-test, for comparing the according to the measurement time, the accuracy after 3 minutes became higher than the case of 4 minutes (t = 4.584, p <.001). Therefore, before 119 arrives performing cardiopulmonary resuscitation for emergency, rescuers need to perform cardiopulmonary resuscitation alternating with others before 3 minutes.

본 연구는 시간 (3분, 4분)에 따른 구령방법이 심폐소생술의 피로도와 정확도에 미치는 영향을 자료로 제시하기 위하여 실험집단과 대조집단의 실험 전 신체적 특성의 동질성을 독립표본 t 검정을 실시하여 동질한 집단으로 나타났다. 집단 별 젖산의 차이를 반복측정 분산분석을 실시한 결과, 시간 (F=7.835, p <.01)과 집단 (F=8.695, p <.01)의 주효과 및 시간과 집단의 상호작용효과 (F=12.582, p <.001) 등에서 모두 통계적으로 유의하게 나타났다. 즉 집단과 시간 (3분, 4분)에 따른 주효과 검정을 Bonferroni방법을 이용하여 실시한 결과에서 실험집단의 젖산 양이 대조집단에 비해 더 많다는 것을 알 수 있었고 (p <.01), 젖산이 실험 전과 3분 후는 차이가 나타나지 않았지만, 실험 전과 4분 후 (p<.05), 3분 후와 4분 후 (p<.05)는 각각 차이를 나타냈다. 다음으로 측정 시간에 따른 정확도를 비교하기 위하여 대응표본 t 검정을 실시한 결과에서 3분 후의 정확도가 4분 후의 정확도에 비해서 더 높게 나타났다 (t=4.584, p <.001). 따라서 응급상황에서 119가 도착하기 전까지 심폐소생술 시 처치자는 심폐소생술을 3분 전에 타인과 교대로 실시해야 한다.
