The Need for Defibrillator Calibration
When it comes to life-saving medical equipment, accuracy and reliability are everything. A defibrillator can mean the difference between life and death in the event of sudden cardiac arrest. To ensure this vital device performs exactly as it should, regular defibrillator calibration and servicing are essential.
Here at Seal Calibration, we calibrate and service more defibrillators per year than any other service provider in the UK. From schools and nurseries to clinics and doctors’ surgeries, we help thousands of organisations ensure their defibrillators are tested, certified, and always ready to use.
But what does calibration actually involve? And how often does it need to be carried out?
Let’s find out.
What Is Defibrillator Calibration?
Defibrillator calibration is the process of testing and adjusting a device to ensure it delivers an accurate and reliable electrical shock, as intended by the manufacturer. It verifies that the defibrillator responds correctly in simulated emergencies and that its output matches precise, nationally recognised standards.
The calibration process typically involves the following steps:
Diagnostic Simulation
Specialist diagnostic test equipment is used to replicate an emergency scenario, allowing the defibrillator’s responses to be measured.
Shock Output Measurement
The energy delivered is tested to ensure it matches the specified voltage and current.
System and Function Checks
Displays, alarms, audio prompts, and other features are thoroughly checked and tested.
Error Review and Clearing
Any error codes logged in the device are identified and, where possible, resolved.
Certification
Once the process is complete, certificate should be issued showing that the device meets UKAS traceable national standards. This is the highest possible field-based testing standard in the UK, ensuring full compliance with rigorous ISO/IEC 17025:2017 standards.
This tried-and-tested process provides peace of mind that the defibrillator is in full working order and ready to save lives when needed.
Why Is Professional Calibration Important?
When someone suffers sudden cardiac arrest, every second counts. If the nearest defibrillator fails, delivers the wrong shock, or malfunctions, the outcome can be fatal. That’s why calibration is paramount – it confirms that your device is safe, accurate, and reliable.
Moreover, regular defibrillator servicing and calibration also ensures compliance with health and safety requirements. Many organisations, from community centres and schools to office buildings and sports stadiums, need an annual defibrillator maintenance record to prove their device is safe and operational.
Key takeaway:
Calibration isn’t just a technical requirement – it’s a safeguard against failure in a life-or-death situation.
How Often Does a Defibrillator Need to Be Calibrated?
One of the most common questions we’re asked is:
How often should a defibrillator be calibrated?
The answer is at least once a year. Annual calibration and servicing ensure:
- Compliance with safety regulations and insurance requirements.
- Early detection of potential issues before they become failures.
- Peace of mind for staff, visitors, and the public who may one day rely on the device.
At Seal Calibration, we recommend that all organisations keep an annual defibrillator servicing schedule. In higher-risk or heavy-use environments, more frequent checks may be advisable.
By making calibration an annual routine, you can be confident your device will work when it’s needed most.
