Which document typically defines the required PM interval for a medical device in a US hospital?
Answer: Manufacturer's service manual
The manufacturer's service manual specifies recommended PM intervals and procedures that biomed departments use to build their maintenance schedules.
What is the primary purpose of calibrating a clinical thermometer used in patient care?
Answer: To verify its accuracy against a known reference standard
Calibration compares the device's output to a traceable reference standard to confirm accuracy within acceptable tolerances.
Which organization publishes ANSI/AAMI standards relevant to biomedical equipment maintenance in the US?
Answer: Association for the Advancement of Medical Instrumentation (AAMI)
AAMI publishes consensus standards and technical information reports widely used by biomedical engineers for equipment maintenance and safety.
A BMET is performing a PM on an infusion pump. Which test is most critical for patient safety?
Answer: Flow rate accuracy test
Flow rate accuracy directly affects drug dosing; an out-of-tolerance pump can deliver under- or over-doses with life-threatening consequences.
What does 'equipment management inventory' primarily track in a biomed program?
Answer: Every device's location, PM schedule, and service history
A complete inventory ties each device to its asset number, location, PM due date, and maintenance history to ensure no device is missed.
Which electrical safety test measures the current that could flow through a patient connected to a device?
Answer: Patient leakage current test
Patient leakage current testing measures stray current that could pass through a patient, per ANSI/AAMI ES60601-1 limits.
