We held an “American Heart Association (AHA) Family & Friends®” CPR Course using one simple-type manikin and assessed chest compression skill by the CPR Skills Measurement System.
As a result of training, there was a significant increase mean chest compression depth (Pretraining : 43.2±10.8mm, post-training : 50.5±7.2mm, P<0.05). The implementation rate for appropriate hand location and full chest wall recoil were significantly higher for females both before and after the training (P<0.05). The implementation rate for appropriate depth and both the mean depth and mean compression rate were significantly higher for males, both before and after the training, with deeper depth and a higher compression rate than females (P<0.05).
We divided the students into the following each three groups based on the mean chest compression rate and the mean chest compression depth. The results of our investigation of the percentage of subjects in each group indicated a significant difference in females only prior to the training (P<0.05).
In addition, 57.1% of females had a depth of P<50 mm after the training, We believe that it is necessary to investigate training methods that take into account the diffrences between males and females in terms of physical strength. In order to increase the quality even further, it is necessary to investigate training methods that emphasize the revisions made in the 2015 JRC Guidelines. We also believe that it is necessary to assess the number of years before re-training designed to maintain an appropriate skill level.
