Medical Equipment Calibration plays a critical role in the reliability of diagnostic processes and, ultimately, the safety of patients. The importance of regular medical equipment calibration cannot be understated.

In top-tier healthcare systems like New Zealand’s, where medical practitioners strive for excellence in patient care, the accuracy of medical equipment is non-negotiable, which brings us to the topic of Medical Equipment Calibration.

In this blog, we shed light on the significance of Medical Equipment Calibration, particularly in the context of New Zealand's healthcare landscape.

What is Medical Equipment Calibration?

Medical Equipment Calibration is the procedure of identifying and rectifying uncertainties and discrepancies in measurements, ensuring that medical equipment measurements are accurate, consistent and within acceptable standards.

The accuracy of medical devices is paramount, directly influencing diagnostic procedures and patient outcomes.

Unlike faults arising from manufacturing, deviations in output often result from continuous use, resulting in inaccurate readings and affecting the internal components over time.

Although deviation for calibration is a common occurrence, medical practitioners and healthcare providers can retain control over the accuracy and performance of medical equipment by scheduling regular maintenance and calibration with a trusted partner like Able Tech.

Distinguishing Calibration from Maintenance

It's crucial to distinguish between calibration and maintenance activities. While maintenance addresses faults in a device, calibration is instrumental in identifying instruments that deviate from the manufacturer's standard baseline readings.

However, the good news is Able Tech offers maintenance and calibration of medical equipment within the same scheduled service visit, asserting peace of mind in the accuracy of your medical equipment.

Calibration Frequency and Tolerance Limits 

Manufacturers typically provide built-in systems and guidelines for calibration processes, along with recommended frequencies. However, users can tailor the calibration frequency based on the instrument's application and usage frequency.

Every device comes with tolerance limits, and if calibration falls within these limits, the device can continue to be used. Conversely, failure in calibration renders the device unusable until corrective actions are taken.

It's noteworthy that during the initial warranty period, unauthorised work may void the warranty. Therefore, healthcare providers in New Zealand should follow up with the supplier and/or manufacturer on the terms and conditions of the warranty.

Documentation: A Pillar of Calibration

In the meticulous process of calibration, comprehensive documentation is imperative.

This includes a Calibration Plan categorised on a monthly, quarterly, and yearly basis, Standard Operating Procedures (SOPs) detailing calibration steps, and a Calibration Results Sheet showcasing actual results and tolerance limits.

Notably, the calibration status is indicated on the device, including the date of calibration and the next due date for calibration. This rigorous documentation process aligns with New Zealand's commitment to regulatory compliance.

Significance of Medical Equipment Calibration in New Zealand Healthcare

Medical devices, irrespective of manufacturer or sophistication, are susceptible to internal wear and tear.

In New Zealand, adherence to calibration processes is not just a best practice; it's a regulatory requirement. The calibration process is essential for detecting erratic readings caused by the natural degradation of internal components, a phenomenon common to even the most advanced manufacturers.

In compliance with regional regulatory bodies, such as the AU/NZS standards, regular calibration is mandatory. The documentation maintained during the calibration process is crucial for routine inspections, ensuring that healthcare providers in New Zealand meet the stringent requirements set forth by regulatory authorities.
