Nondurable parts are those components of the device that have been identiп¬Ѓed either by the device manufacturer or by general industry experience as needing periodic attention, or being subject to functional deterioration and having a useful lifetime less than that of the complete device. вЂвЂPreventive maintenance is the inspection, cleaning, lubricating, adjustment or replacement of a deviceвЂ™s nondurable parts. These three terms are deп¬Ѓned by the AAMI/Industry Task Force as follows. According to the document developed by the AAMI/Industry Task Force, the term scheduled (planned) maintenance вЂвЂconsists of some or all of the following activities: cleaning decontamination preventive maintenance calibration performance veriп¬Ѓcation and safety testing.вЂ™вЂ™ Among these activities, the three key activities are (1) preventive maintenance (PM) (2) performance veriп¬Ѓcation (PV) or calibration and (3) safety testing (ST). However, many still use the traditional term preventive maintenance rather than this new, more carefully deп¬Ѓned term. Servicing and Remarketing while developing a document for submission to the FDA entitled вЂвЂJoint Medical Device Industry Proposed Alternative to the Regulation of Servicers, Refurbishers, and RemarketersвЂ™вЂ™ (6). The term вЂвЂscheduled (planned) maintenanceвЂ™вЂ™ was introduced in 1999 by a joint AAMI/Industry Task Force on If the unit detects a problem during one of the periodic self-tests, the unit beeps and displays a п¬‚ashing red or a solid red warning signal on the status indicator (5). The manufacturer also states that the FR2 Гѕ requires no calibration or veriп¬Ѓcation of energy delivery.

These activities include daily and weekly self-tests to verify readiness for use and more elaborate monthly self-tests that verify the shock waveform delivery system, battery capacity, and internal circuitry. For example, the Philips HeartStart FR2 Гѕ deп¬Ѓbrillator performs many maintenance activities itself. In modern equipment, the need for performance and safety testing is greatly reduced because of the design and self-testing capability of the equipment (3,4). Device reliability is an intrinsic function of the design of the device and cannot be improved by PM. It has been argued that current medical devices are virtually error-free in terms of engineering performance. Also, equipment failures that are attributable to incorrect set up or improper use of the device or the use of wrong or defective disposable accessory cannot be prevented by doing PM (2). Today, medical equipment uses electronic components that fail in an unpredictable manner, and their failure cannot be anticipated through measurements and checks performed during a PM (1). The term вЂвЂcorrective maintenanceвЂ™вЂ™ is often used instead of the term вЂвЂrepair.вЂ™вЂ™ PM refers to the work performed on equipment on a periodic basis and should be distinguished from вЂвЂrepairвЂ™вЂ™ work that is performed in response to a complaint from the equipment user that the device has failed completely or is not working properly. The term preventive maintenance has its origins with mechanical equipment that has parts that are subject to wear and need to be restored or replaced sometime during the useful lifetime of the device. The primary objective of a PM program for biomedical equipment is to prevent failure, which is achieved through (1) detecting the degradation of any non-durable parts of the device and restoring them to like-new condition (2) identifying any signiп¬Ѓcant degradation of the performance of the device and restoring it to its proper functional level and (3) detecting and repairing any partial degradation that might create a direct threat to the safety of the patient or operator. The other functions include incoming inspection/testing, prepurchase evaluation, coordination of outside equipment service, hazard and recall notiп¬Ѓcation, equipment installation, equipment repair and upgrade, purchase request review, equipment replacement planning, device incident review, and regulatory compliance maintainance. Preventive maintenance (PM) is one of the many functions of a clinical engineering department.
