Operation theatre validation built around patient safety
Vanavil Calibrations validates hospital operation theatres against the environmental parameters that protect surgical patients from infection risk — on-site, documented, and ready for your hospital's accreditation file.
A surgical environment is only as safe as its last validation
An operation theatre is a controlled environment built for one purpose: keeping a surgical site free of contamination risk. Airflow patterns shift, filters load up, pressure differentials drift as doors are used and equipment changes — none of it visible during a case. Operation theatre validation is the structured measurement process that confirms the OT is still performing the way it was designed to, before drift becomes an infection-control risk.
This is distinct from a pharmaceutical manufacturing cleanroom in one important way: the framing is patient safety and surgical outcomes, not product yield. Our OT validation service is built around that context — for conventional operation theatres and for the modular operation theatres many hospitals now build with, using prefabricated wall and ceiling panel systems designed for infection control.
Patient safety starts with a validated OT environment
Surgical Site Infection Control
Airborne particulates and poor airflow directly raise the risk of surgical site infection in an open procedure.
Patient Safety
Every parameter we test exists to protect the patient on the table — not just to satisfy a checklist.
Hospital Accreditation
Hospital accreditation and quality frameworks expect documented, ongoing evidence that OT environments are under control.
Environmental parameters covered in every OT validation
- Airborne particle count
- Airflow velocity and pattern
- HEPA filter integrity
- Differential pressure between the OT and adjoining areas
- Temperature and humidity
- Light intensity for surgical work
- Sound level

OT Assessment
We review the theatre's construction — conventional or modular — and confirm which parameters need testing.
On-Site Testing
Testing is carried out against ISO IEC 17025:2017 procedures using calibrated instruments.
Documented Report
You receive a report with results per parameter, ready for your hospital's quality and accreditation records.
Corrective Guidance
Where a parameter falls outside expectation, we advise on next steps to protect patient safety.
