Medical Equipment Predictive vs Preventive Maintenance

ERD’s biomedical technicians bring the skill sets and scheduling flexibility you need to supplement and support your hospitals clinical engineering staff.

Maintenance program strategies must be managed differently when it comes to older technology devices compared to newer technology devices, to maintain the reliability of the medical devices and prevent device failure. Newer technology devices utilize predictive maintenance strategies defined by the manufacturers’ recommendations and daily-programmed self-tests that should be done. Predictive solutions are highly dependent on third-party artificial intelligent software to collect the data and relay the real time information back to the manufacturer. Older technology devices, don’t allow for such technology thus needing preventative maintenance schedules to perform periodical performance verification and safety testing (PVST) in accordance with international standards and manufacturers’ recommendations.

Predictive Maintenance

Predictive maintenance is similar to a screening or a precautionary procedure for an individual with a higher risk for a particular disease. In the instance of a hospital or clinic, predictive maintenance monitors real time conditions of device parameters through AI systems, which gives you the data required to make the smartest decision. Once a pattern is detected that indicates a possible future failure, predictive maintenance protocol is triggered to conveniently schedule a work order, preventing future device failures.

Preventative Maintenance

Preventative maintenance is similar to a physical checkup. The biomedical technician performs the maintenance tasks while the device is still running smoothly to avoid future breakdowns or emergency maintenance issues. Just like a physical can help prevent illness or disease and lengthen your life, preventative maintenance can prevent equipment failures and extend the functional life of the medical device. A functional medical device is always more profitable.

Experienced maintenance managers must make smart decisions on which machines requiring preventative maintenance work and how often it is needed. The theory is that the preventative maintenance to corrective maintenance work ratio should be about 6 to 1. This assumes that the preventative maintenance inspections should reveal some type of corrective work that needs to be completed on an average of every 6 times preventative maintenance has been done. The assumption is that, if the ratio is greater than 6:1 you are performing preventative maintenance too often; if the ratio is less then 6:1, you are not performing it often enough. John Day, Jr., Manager of Engineering and Maintenance at Alumax of South Carolina has proved the “6 to 1 Rule”, when Alumax of South Carolina was certified as the first “World-Class” maintenance organization.

Establishing a maintenance program comprised of both preventative and predictive maintenance for your medical equipment will ensure you are protecting your patients by meeting industry-leading quality standards.

If your healthcare facility is in need of a proactive maintenance schedule, call ERD today. You can trust that each item will be tested with the utmost attention to detail.
