ABSTRACT

PURPOSE:

To minimize an interruption in chest compression, reduce the hands-off time, the American Heart Association has recommended changing the ratio of chest compression to ventilation ratio to 302. However, current studies have shown that the hands-off time was >10 seconds with that method. For this reason, we reasoned that a chest compression to ventilation ratio of 151 would be a more suitable way to reduce hands-off time because this ratio will not change the total compression and ventilation count.

METHODS:

The subjects were asked to perform CPR for 5 cycles with a compression to ventilation ratio of 302. The subjects rested for 5 minutes, then performed CPR with a compression to ventilation of 151. The skill performance was measured and analyzed using a statistical program.

RESULTS:

In the group which performed CPR with a chest compression to ventilation ratio of 302, the average number of compressions per minute was 76+/-9, while at a chest compression to ventilation ratio of 151, the average number of compressions per minute was 68+/-9. Between the compression to ventilation ratios of 302 and 151, the count gap was 8.3+/-3.2. When CPR was performed at a chest compression to ventilation ratio of 302, the average hands-off time was 9.3+/-1.9. When CPR was performed at a chest compression to ventilation ratio of 151, the average hands-off time was 6.7+/-1.3. Between chest compression to ventilation ratios of 302 and 151, the time gap of the average hands-off time was 2.7+/-1.2 seconds.

CONCLUSION:

When the chest compression to ventilation ratio was 151, the hands-off time was significantly reduced, but the compressions per minute were also reduced.
