Results The compression rate and the too fast frequency in the depth display group were significantly higher than those in the music metronome group, and the total compression times in depth display group were significantly higher than either in music metronome group or in blank control group (times 152.73☒7.05 vs. The quality of chest compression among the four groups of volunteers was compared. At the same time, the correct compression ratio, correct ventilation ratio, the chest compression fraction 2 (CCF2) displayed on the human electronic displayer of the manikin were used as the review criteria. The chest compression fraction 1 (CCF1), compression depth, compression rate, too slow frequency, too fast frequency, too shallow frequency, the total times of compressions, the correct times of compressions, correct rate, and the rate of compression retention were record as preliminary evaluation data by using the dual sensor and the pressure sensor built in the chest compression feedback device.

A chest compression feedback device was placed on the pressing point, on which the participants places the hand for CPR.

Each participant performed 5 cycles of CPR on a manikin. In phone metronome group, a mobile phone metronome was applied in the duration of CPR, with a frequency of 110 beats per minute, beat 2/4 in the music metronome group, it was accompanied by the music Staying Alive during the compression period, with frequency of 107 beats per minute, beat 4/4 in depth display group, a model electronic displayer was used in the duration of the compressions to feedback the real time compression depth and its rebound situation in CPR there was no any intervention measure in blank control group. They were divided randomly into phone metronome group (n = 16), music metronome group (n = 15), depth display group (n = 22), and blank control group (n = 20). Finally, 73 participants being volunteers were enrolled. Methods There were 84 participants who were the first year standardized training residents recruited from Guangdong Provincial Hospital of Chinese medicine during July to August 2016, and eleven of them were excluded because of incomplete chest compression data collected from the feedback system. Objective To investigate the influence of different prompt measures on the quality of cardiopulmonary resuscitation ( CPR) chest compressions in the standardized training of residents in Chinese medicine hospitals.
