1) Effectively reduce the failure rate of equipment in the early failure period and wear failure period, reduce the maintenance workload, thus reduce the maintenance costs in operation, and reduce the loss due to downtime and overhaul, and play a preventive role.

2) effectively extend the accidental failure period, that is, to extend the service life of equipment.

3) improve the quality of the application of safety equipment to ensure the safety of patients and users.

4) to ensure that the equipment is in the best working condition, improve the equipment intact, make it to maximize its effectiveness.

5) Reduce the occurrence of wrong operation of the personnel, and timely feedback of the equipment in use to enhance the quality of clinical equipment. The feedback gathered through the PM can improve the reliability and usability of the purchased instrument. As one of the methods of on-the-job training of medical engineers, PM improves the technical quality of medical engineers and promotes the sustainable development of hospital construction in terms of personnel training.

6) If the managers, technicians, maintenance personnel and operators are still working on an advanced level, improper use and improper maintenance of medical equipment will result in frequent failures, increased repair time, delayed patient examination and further May lead to outflow of patients, reduce social benefits, the ultimate impact on the development of the entire hospital.
