The quality of chest compression affects survival after sudden cardiac arrest, particularly when it occurs out of hospital. Pharmacy students should acquire basic life support skills as part of the model core curriculum of pharmacy education. Here, we trained first-year students at the Faculty of Pharmacy to deliver cardiopulmonary resuscitation and used a manikin with a real-time feedback device that quantified chest compression skills. Students were classified into shallow compressions (SC; <50 mm) and deep compressions (DC; ≥50 mm) groups based on the depth of chest compressions measured prior to training. After training, the mean compression depth (mm) was significantly shallower for the SC, than the DC group and many students in the SC group did not reach a depth of 50 mm. Similarly, students were classified into slow compression rate (SR; ≤120/min) and rapid compression rate (RR; >120/min) groups based on the results of training in the rate of chest compressions. Significant differences in mean compression rates were not found between the groups. However, correct compression rate (%), the percentage of maintaining 100-120 compression/min was significantly higher in the SR, than in the RR group. Chest compression rates correlated with compression depth, and chest compression tended to be too shallow in group that was too fast. The quality of chest compression might be improved by delivering chest compressions at a constant rate within the recommended range.
