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.
胸外按压质量影响心脏骤停后的生存率，尤其是在院外发生时。药学专业学生应掌握基本生命支持技能，作为药学教育标准核心课程的一部分。在此，我们对药学院的一年级学生进行了心肺复苏培训，并使用了带有实时反馈装置的人体模型，该装置可对胸外按压技能进行量化。根据训练前测量的胸外按压深度，将学生分为浅按压（SC；<50 mm）组和深按压（DC；≥50 mm）组。训练后，SC组的平均按压深度（mm）明显比DC组浅，且SC组许多学生未达到50 mm的深度。同样，根据胸外按压速率的训练结果，将学生分为慢按压速率（SR；≤120次/分钟）组和快按压速率（RR；>120次/分钟）组。两组之间的平均按压速率未发现显著差异。然而，正确按压速率（%），即保持100 - 120次/分钟按压的百分比，SR组明显高于RR组。胸外按压速率与按压深度相关，按压过快的组胸外按压往往过浅。在推荐范围内以恒定速率进行胸外按压可能会提高胸外按压质量。
