The Rapid Cycle Deliberate Practice (RCDP) is a simulation-based training approach that gradually enhances muscle memory through repeated practice and targeted feedback in real-life situations. This article aims to investigate the RCDP training method's effectiveness based on feedback in assessing nursing students' cardiopulmonary resuscitation (CPR) quality. The study included 48 nursing students from a particular school's 2020 cohort. The students were randomly divided into two groups using computerized randomization. The experimental group (Group A, n=24) used the RCDP method to simulate CPR under the guidance of a teacher, while the control group (Group B, n=24) used traditional methods for practice. The students received one hour of theoretical training and two hours of practical training. Knowledge questionnaires were distributed before and after the theoretical training, and the SimPad Plus was used to collect student assessment data after the practical training. The quality of the skills assessment of the two groups was compared, including the number of compressions, average compression depth, compression recoil pass rate, compression depth pass rate, compression frequency, number of ventilations, ventilation volume, and student satisfaction with teaching. The results showed statistically significant differences in the pass rates between the two groups in terms of total compressions, compression frequency, ventilations, and total ventilations (P<0.01). The experimental group had a higher pass rate of compression recoil than the control group (P<0.01), a shorter average interrupt time during compression (P<0.01), and a higher pass rate of compression depth (P<0.01). The CPR quality of nursing students was improved, enabling them to perform CPR more accurately and effectively. Learner feedback was positive, indicating that they believed the experience would improve their clinical performance. In conclusion, the RCDP training method based on SimPad Plus feedback, through expert feedback, repeated practice, and real-time feedback from simulated patients, is beneficial in improving the quality of CPR among nursing students.r of 60-point.
