The effect of applying real-time feedback system to improve the quality of chest compression

Abstract

Objective To observe the effect of applying CPR real-time feedback system to improve the quality of chest compression. Methods 110 staff who from emergency department and pre-hospital care practiced CPR on a resuscitation manikin for 2min according to the 2015 AHA guideline update for CPR recommended requirements. First, applied the Zoll CPR feedback technical report system but operator were back to the computer monitor. Observed and recorded each operator at an average rate of Chest compression (times/min), average depth (cm), Chest compression release velocity, (CCRV) (centi - inches/s). Then practice again for 2 min chest compression in the face of the feedback system after an hour rest. The computer system recorded the above parameters and then data analysis. Results Before and after the application of feedback system, the effective rate of chest compression respe ctively was (20.25±26.89)% vs. (70.16± 20.18)%; Mean Compression depth respectively was ( 5.15±0.76)cm vs.(5.52±0.29)cm.Excessive Compression depth and Compression depth were significantly lower than the percentage of the application before 43.64%vs. 10% ; 14.55%vs. 0.09%. The mean chest compression rate respectively was (102.26±6.76)times/min vs.(121.29±9.89)times/min ; The mean CCRV respectively was (1 430.81±218.79)centi-inches/s vs.(1 575.62±135.71) centi-inches/s, differences were statistically significant (P<0.01, n=110). Conclusions Monitoring and applying the CPR real-time feedback system can effectively improve the quality of chest compression.
