Patient monitors give clinical staff the numbers they rely on moment to moment — which means a monitor reading even slightly inaccurately is a genuine patient safety issue, not just a compliance formality. Nova Biomedical has calibrated and serviced patient monitors for hospitals, GP practices, and aged care providers across Queensland, New South Wales and Western Australia for over 25 years, and we’re ISO9001:2015 certified for the quality systems behind that work.
What’s Included in Our Patient Monitor Calibration Service
- Accuracy verification against manufacturer specifications for parameters such as ECG, SpO2, NIBP, and temperature, depending on the monitor’s capabilities.
- Functional testing of alarms, displays, and battery backup, confirming the monitor performs reliably when it matters.
- AS/NZS 3551 electrical safety testing, commonly performed alongside calibration in the same visit.
- Calibration certificates and service records, ready to file for accreditation and internal quality assurance purposes.
Who Needs This Service
Any facility using patient monitoring equipment in clinical care — hospitals, GP and specialist practices, aged care facilities, and ambulance services. Monitor accuracy and maintenance sits within the equipment risk management expectations of the NSQHS Standards and Aged Care Quality Standards. See how this fits into NSQHS Standards compliance.
Common Issues We Find
- Monitors overdue for calibration that are still in active clinical use because the due date wasn’t tracked centrally.
- Alarm settings drifting from clinical protocols over time as devices are moved between wards or reconfigured.
- Battery backup that’s degraded, only discovered during an actual power interruption rather than through routine testing.
FAQ
How often should patient monitors be calibrated?
Typically annually, though higher-use monitors or those in critical care settings may warrant more frequent checks — we can advise based on your equipment and usage.
Can you service multiple monitor brands and models?
Yes, we work across a range of patient monitoring equipment used in Australian hospitals and clinics.
Is electrical safety testing included with calibration?
It’s commonly scheduled together, since both are typically due on similar cycles — we can coordinate this for your site.
What happens if a monitor fails calibration?
We flag it immediately and discuss repair or replacement options, so it’s taken out of clinical use until it’s confirmed accurate.
Who We Provide This Service To
Patient monitor calibration is a routine part of equipment testing programmes for hospitals and aged care facilities.
What Patient Monitor Calibration Involves
Patient monitor calibration verifies that each measurement parameter produces accurate readings within the manufacturer’s specified tolerances. Our biomedical engineers use calibrated reference equipment to test:
- ECG — heart rate accuracy, waveform amplitude, and lead-off detection
- SpO2 — oxygen saturation accuracy across the clinical range, probe condition assessment
- NIBP — systolic, diastolic, and mean arterial pressure accuracy against a calibrated reference manometer
- Temperature — probe accuracy verification where fitted
- Alarm systems — verification that clinical alarms trigger at correct thresholds, as required under NSQHS Standards
Results are provided in a calibration certificate suitable for NSQHS Standards, RACGP, and Aged Care Quality Standards accreditation. We typically combine patient monitor calibration with AS/NZS 3551 electrical safety testing in a single visit — covering both compliance requirements in one attendance with unified documentation.
Monitors We Calibrate
We calibrate patient monitors from all major manufacturers including Philips, GE, Mindray, Nihon Kohden, and Spacelabs — Nova Biomedical holds Philips Authorised Service Provider (ASP) status. We also calibrate standalone devices — dedicated pulse oximeters, handheld blood pressure monitors, and single-parameter ECG devices — which need the same periodic calibration as full bedside units if they’re used for clinical decision-making.
Remote Monitoring & Predictive Maintenance
For Philips patient monitoring fleets, we also support Philips Remote Services — connected monitoring that can flag device performance issues before they cause a failure, rather than waiting for the next scheduled calibration to catch it. It sits alongside our on-site calibration and PPM contracts as part of a proactive equipment management approach, and complements — rather than replaces — your AS/NZS 3551 compliance testing.
