How often should EKG machines be calibrated?

Calibration of EKG machines is a critical practice to ensure that they provide accurate measurements of electrical activity in the heart. The correct answer highlights the recommended frequency of calibration, which is typically once a month or according to specific guidelines provided by the manufacturer or medical regulations. Regular calibration is essential to maintain the precision of the readings, as environmental factors, usage, and time can affect the performance of the equipment.

Monthly calibrations help identify any discrepancies that may arise between the machine's output and the actual cardiac activity. Some facilities might have specific protocols that dictate the calibration schedule based on their patient population or the volume of EKGs performed. These guidelines are established to ensure patient safety and the reliability of the tests performed.

Calibration before daily use is excessive and may not be practical, while calibrating every week or twice a year might not align with the standard protocols recommended by manufacturers or regulatory bodies. The established frequency ensures that EKG machines maintain their functionality without overburdening the staff or resources.
