심폐소생술 1인과 2인 구조자의 30:2 흉부압박-환기 비가 심박수와 혈중젖산농도에 미치는 영향

다국어 초록 (Multilingual Abstract)

The purpose of this experiment was to recognize the effect of Heart Rate, Blood Lactate Concentration by changes of 30:2 Compression-Ventilation ratio in the Rescuer. Compression to ventilation ratios of 30:2 are recommended in the 2005 guidelines for Cardiopulmonary Resuscitation. Heart rate, blood lactate concentration were evaluated for students randomized to perform 30:2 Cardiopulmonary Resuscitation 10 minutes at either 1 rescuer or 2 rescuer on a recording Cardiopulmonary Resuscitation Manikin. There are twenty students participated in this experimental study. Heart rate and lactate in 1 rescuer were also significantly higher than 1 rescuer after second minute. Fatigue associated with Cardiopulmonary Resuscitation reach maximal steady state at 2-3 minutes. The most significant factor determinate fatigue is number of rescuers. Rapid and exact rescuer position change is most important measure to improve Cardiopulmonary Resuscitation quality. Enhancement of physical strength also can prevent rescuer`s fatigue.
