[The Effect of Using a Real-Time Feedback Device on the Quality of Cardio Pulmonary Resuscitation (CPR)]

Cardiopulmonary resuscitation (CPR) is a standard procedure delivered to patients experiencing cardiac arrest. CPR quality is associated with the rate of survival of patients with cardiac arrest.

To determine the efficacy of a real-time feedback device in terms of improving CPR performance quality and CPR self-efficacy in nursing staffs.

A total of 72 nursing staffs were enrolled in this randomized trial (intervention n = 38, control n = 34). A real-time feedback device was used to monitor CPR quality and provide real-time feedback. The participants performed CPR on a manikin with (intervention) or without (control) feedback for 5 cycles (about 2 minutes). Data on participant demographic characteristics and CPR self-efficacy scores were also collected.

The intervention group performed better in terms of the compression adequate rate ratio (76.3 vs. 52.3, p < .001), mean depth (52.8 mm vs. 50.6 mm, p = .003), adequate depth ratio (65.6 vs. 55.1, p = .014), quality of CPR performance score (44.1 vs. 26.1, p < .001), proportion of excellent CPR (60.5 vs. 26.5, p < .001), and CPR self-efficacy score (40.22 vs. 36.71, p < .001). However, no significant differences between the two groups were found in terms of proportion of complete chest decompression and chest compression fracture (p >.05).

Using a real-time feedback device may not only significantly improve the quality of CPR performed on a manikin but also improve self-confidence to implement CPR correctly in practice.
