At rest vs. in operation

At the latest NVMM symposium our colleague Mike van der Heijden showed numerous CFD (Computational Fluid Dynamics) simulations of operating rooms. These simulations proved that there is a significant difference in airflow and particle dispersion between ‘at rest’ vs ‘in operation’.

The current design process of an operating room is mainly based on:

  • simplified design principles
  • in-situ (‘at rest’) cleanliness measurements after completion

But the airflow pattern and particle dispersion is influenced significantly by people, lights and e.g. instrument tables.

The use of computional fluid dynamics

Computational fluid dynamics (CFD) breaches the gap between the design phase of an operating room, calibration, testing when built and between the actual situation in use.
