Abstract

PURPOSE: In an emergency, the quality of CPR prior to hospital arrival is a very important component for the survival of victims. We want to know differences in chest compression quality performed by groups that have variant experiences of CPR, and automatic CPR machine on the floor, or in an ambulance moving at 40 km/hr, or at 80 km/hr.
METHODS
We analysed the chest compression quality of each group, and that performed on the floor, in an ambulance moving as 40 km/hr, and at 80 km/hr. We measured the following factors: mean compression depth; mean compression rate; exact performance percentile; and the compression error through too deep, too weak, wrong compression location, and no full recoil.
RESULTS
In the student-nurse group, the quality of chest compression performed on the floor was better than that performed in a moving ambulance. In 119 member group, chest compression performed in an ambulance moving as 40 km/hr was better than that performed in an ambulance moving at 80 km/hr. The use of an automatic CPR machine, there were no differences in chest compression quality in all circumstances. In comparing each group, compression quality of the 119 member group and the automatic CPR machine group was better than that of the student nurses.
CONCLUSION
In the group with real CPR experience, there were no differences between chest compression performed on the floor and that performed moving at 40 km/hr. Chest compression performed moving as 40 km/hr is better than that performed moving at 80km/hr. In the group without CPR experience, chest compression performed on the floor is better than that performed in a moving ambulance.
