Performance Testing and Data Analysis of Defibrillators
Objective To provide guidance for preventive maintenance and procurement decisions through performance testing and data analysis of defibrillators in use from different brands.Methods According to the national measurement standards,the performance of the defibrillator in use was tested and the data were collected,including the discharge energy,charging time,synchronization delay time and heart rate.The parameters of data were tested by SPSS software.Results The actual discharge energy analysis showed no significant differences in discharge energy of 30 J(P=0.118>0.05)and 100 J(P=0.084>0.05)among different brands of defibrillators.However,there were significant differences of discharge energy of 200 J in actual discharge energy(P<0.001),charging time(P=0.001<0.05),and synchronizing delay time(P=0.001<0.05).There was no significant correlation between duration of use and the deviation in maximum defibrillation energy(r=-0.009,P=0.956>0.05),while there was a significant positive correlation between duration of use and charging time(r=0.556,P<0.001).Conclusion Fully utilizing the data from the usage process of medical devices can assist in equipment management decisions and improve the clinical quality and level of precision in medical device utilization and management.
