Abstract Objective To investigate the effect of using real-time feedback system of cardiopulmonary resuscitation (CPR) with air deflating. Methods A study was carried out on the manikin, 2 min of external cardiac compression was implemented by the medical and nursing staff in the intensive care department of our hospital. A hard board was located under the manikin and the air mattress was deflating in the control group; Additionally, the observation group used LinkCPR (feedback system) to correct the pressing depth and frequency. The results were compared. Results The mean compression depth of the observation group was (56.11±1.79) mm, which was higher than that of the control group namely (52.78±1.56) mm. And the mean accuracy rate and retention rate were 64.89% and 31.29% respectively, which were superior to those of control group namely 56.62% and 39.23%. The data had significant differences (P<0.05). The compression frequency of the observation group and the control group was (107.44±3.57) time/min, and (111.00±4.25) time/min, respectively. The data had no significant difference (P>0.05), which might because the time of compression is short. It was found that the pressure depth and frequency of the observation group were more stable, especially in the second half of compression, the control group had a significant reduction in the accuracy rate compared with the observation group. Conclusion The use of LinkCPR can ameliorate the problem of pressing too shallow, improve the accuracy of pressing and increase the stability of CPR with air deflating.
