ABSTRACT
Objective:In view of the different kind of equipment to develop proprietary standardization of medical equipment preventive maintenance template, and make a quantitative evaluation of effects.Methods: Set up the experimental group and control group, compare maintenance data and parameters of the quality control.Results: According to the standardization of the preventive maintenance of patient monitor template, maintenance data improved, quality indicators improved significantly.Conclusion: The establishment of the standardization of medical equipment preventive maintenance template, can improve the rate of running machines, security equipment in the best state operation, reduce the equipment failure risk, ensure the safety of the use of the equipment.
ABSTRACT
Objective:Through the application of remote diagnosis system in medical equipment operation maintenance analysis, clarify the significance of the remote diagnosis technology.Methods:Combined with the actual case, from the breakdown maintenance, preventive maintenance, online training, and other aspects to explore remote diagnosis technology in the medical equipment application and expand operations.Results:Using the remote diagnosis technology can reduce the failure rate, monitor system operation state and environment parameter, improve the efficiency of management of medical equipment.Conclusion: remote diagnosis technology make full use of the manufacturers of professional and technical resources, early detection equipment problems, provide prospective judgment, ensure the equipment running in the best condition.
ABSTRACT
ObjectiveTo evaluate the value of 24 h dynamic electrocardiogram (DCG) and treadmill exercise testing(TET) in diagnosing coronary heart disease(CHD),and analyze relevant index between coronary arteriography(CAG) and treadmill exercise testing.MethodsOne hundred and forty-nine borderline cases of coronary heart disease were enrolled.Every patient was examined by DCG,TET,and CAG,compared the diagnostic value of TET combined with DCG and TET or DCG alone,and record the increased heart rate during the first minute( △ HRl min) of TET and systolic blood pressure(SBP) recovery.The patients were divided into a CHD group and a non-CHD group according to the results of coronary angiography.ResultsThe sensitivity rate was 78.57％ and specific rate was 70.77％ by means of TET.The sensitivity rate was 61.90％ and specific rate was 66.15％ by means of DCG.The sensitivity rate was 95.23％ ,specific rate was 55.38％,positive predictive value was 73.39％ and negative predictive value was 90.00％ by parallel way of DCG and TET,its sensitivity rate (95.23％) and negative predictive value (90.00％ ) were more than those of DCG or TET alone.The sensitivity rate was 52.38％,specific rate was 95.38％,positive predictive value was 93.62％ and negative predictive value was 60.78％ by serial way of DCG and TET,its specific rate (95.38％) and positive predictive value (93.62％ ) were more than those of DCG or TET alone.The number of men in the CHD group was higher than the number of women.Ratio of systolic blood pressure recovery(rSBPR) in the CHD group was significantly higher than that in the non-CHD group ( P ＜ 0.01 ).Conclusion It can obviously enhance the sensitivity rate and specific rate if combined TET with DCG.Patients with CHD have a delayed decline in SBP during recovery which can be one of the indexes to estimate the extent of myocardial ischemia and coronary artery lesion.
