Medical devices play an important role in the healthcare sector, as they are designed to diagnose illnesses, monitor patient’s conditions, and treat health problems.
Therefore, these devices must work correctly and as intended. But how can this be ensured? The answer is medical (or diagnostic) equipment calibration.
But what is that and why is it important? Keep reading to find out everything you need to know!
What is medical equipment calibration?
Medical equipment calibration is the process of verifying and adjusting medical devices so that their measurements and readings align with established standards.
This process involves comparing device outputs and reference values, as well as making the necessary corrections to eliminate errors.
Calibration takes place to ensure the accuracy and reliability of medical equipment.
Calibration of medical equipment: Why is it important?
Medical devices are essential in the healthcare sector, but their accuracy can decline over time due to frequent use.
Proper and regular calibration keeps them precise and reliable, ensuring the accuracy of test results. Let’s see why calibration is important a bit more explicitly:
- More accurate diagnoses → Proper calibration ensures that the readings, images, and data of medical devices are accurate, which can lead to the minimisation of misdiagnoses.
- Better and more effective treatments → Medical devices used for treatment (such as infusion pumps, nebulizers, insulin pumps, etc.) administer medication with precision. Even minor deviations can lead to inadequate treatment or dangerous overdoses.
- Lower costs → Regular calibration prevents expensive equipment repair and replacements.
- Regulatory compliance → Testing and calibration of medical equipment is crucial for meeting regulatory standards.
How to calibrate medical (diagnostic) equipment?
The calibration process varies depending on the device. However, some fundamental principles apply to most calibration procedures:
- Comparing device readings with an established standard → The device’s readings are compared to a recognised standard, ensuring they are universally accurate.
- Making necessary adjustments → In case discrepancies occur, the device needs to be adjusted and corrected so that its readings align with the established standards.
- Documentation → The whole calibration process needs to be documented, from the beginning to the end. The date of the process, and any deviations noted or corrections made should be noted down.
What medical equipment needs calibration? [List]
In case you are wondering, here is a list of the most common medical equipment that needs calibration:
- ECG (electrocardiogram) machines
- Thermometers
- Infusion pumps
- Defibrillators
- Medical scales
- CO (carbon monoxide) meters
- Otoscopes
- Ear syringes
- Spirometers
- Ultrasonic cleaners
- MRI (Magnetic Resonance Imaging) machines
- Blood pressure monitors (by the way, read our article on how to choose the best blood pressure monitor for home use)
- Hyfrecators
- Doppler ultrasound machines
How often should medical equipment be calibrated?
There is no single answer to how often your medical equipment should be calibrated.
Several factors influence the calibration frequency:
- Type of equipment
- Usage (more frequent usage means that more frequent calibration is needed)
- Environmental conditions (exposure to extreme temperatures or humidity can affect accuracy)
- Manufacturer recommendations
However, there are some cases when you can tell that your medical device needs calibration. In general, you need to calibrate your equipment when:
- You are about to use a device for the first time.
- You have used a device a certain number of times (or a certain number of hours, according to the manufacturer’s guidelines).
- Device readings are clearly incorrect or unexpected.
- The device has been dropped, vibrated, or suffered damage that may have affected its accuracy.
Medical (diagnostic) equipment calibration – Summary
Medical equipment calibration is not optional — it is essential!
Regular checks ensure medical devices are precise and reliable, their readings or results are correct and the patients are diagnosed and treated correctly.
