What Is Operation Theatre Validation?
Operation Theatre Validation is the process of testing and documenting whether an operating theatre is maintaining the required air cleanliness, airflow, pressure and environmental conditions for safe surgical use.
The validation scope may include HEPA filter integrity testing, air velocity measurement, air-change calculation, airborne particle counting, recovery testing, room differential pressure measurement, airflow pattern testing, illumination measurement and noise-level testing.
Why Is Operation Theatre Validation Important?
Operating theatres are critical environments where controlled ventilation and air cleanliness help reduce contamination risks during surgical procedures.
Validation helps healthcare facilities:
- Confirm HEPA filter integrity
- Verify air-change performance
- Check room pressure relationships
- Verify airborne cleanliness
- Assess airflow direction
- Identify ventilation-performance issues
- Support quality and accreditation records
- Maintain documented theatre performance
When Should an Operation Theatre Be Validated?
Operation Theatre Validation may be required:
- During initial commissioning
- At periodic validation intervals
- After HEPA filter replacement
- After AHU maintenance
- After ventilation modification
- After theatre refurbishment
- After major repair work
- Following abnormal particle-count results
- Following pressure or airflow problems
- When required by hospital quality procedures
Operation Theatre Validation conditions
Before Validation
The Operation Theatre should be cleaned, available for testing and operated under the agreed condition with access to air terminals, HEPA filters, controls and monitoring points.
Operating Condition
The ventilation and air-conditioning system should be operated under the agreed normal condition for sufficient time to allow airflow, pressure and temperature conditions to stabilise before testing.
After Maintenance
Where validation follows HEPA filter replacement, AHU servicing, ventilation modification or refurbishment, the applicable tests should be completed before the theatre is returned to routine clinical use.
Operation Theatre Validation Services
The calibration scope is selected according to the cabinet type, airflow configuration, application, client protocol and agreed acceptance criteria.
HEPA Filter Integrity Testing
Checks HEPA filter media, seals and installation for leakage and verifies that filtered air is supplied through the intended filtration path.
- Filter-media leakage
- Seal and frame leakage
- Scan-test observations
- Pass/fail result
Air Velocity & Air Change Calculation
Measures air velocity and calculates the number of air changes provided within the Operation Theatre.
- Air velocity readings
- Supply-air volume
- Room volume
- Air changes per hour
Particle Count Test
Measures airborne particle concentration to assess the cleanliness level of the theatre under the agreed test condition.
- Sampling locations
- Particle-size channels
- Particle concentrations
- Cleanliness result
Recovery Test
Evaluates how quickly the ventilation system restores the required cleanliness condition after a controlled particle challenge or disturbance.
- Initial particle level
- Recovery measurements
- Recovery time
- Final cleanliness condition
Room Differential Pressure Measurement
Measures the pressure relationship between the Operation Theatre and adjacent spaces to verify the intended direction of airflow.
- Theatre pressure
- Adjacent-room pressure
- Pressure differential
- Airflow direction
Airflow Pattern Test
Uses smoke or another suitable visualisation method to observe the movement and direction of air within the theatre.
- Airflow direction
- Turbulence observation
- Reverse-flow identification
- Air movement around critical zones
Light Intensity Measurement
Measures illumination within the theatre to verify that the required lighting level is maintained.
- Measurement locations
- Lux readings
- Working-area illumination
- Comparison with acceptance criteria
Noise Level Measurement
Measures ambient and operating noise within the theatre.
- Measurement position
- Ambient noise
- Operating noise level
- Comparison with acceptance criteria
Depending on the theatre configuration and agreed scope, Aeromech may also provide:
- Temperature measurement
- Relative humidity measurement
- Airflow visualisation
- AHU performance checks
- Pressure-monitoring verification
- Supply and return-air assessment
