The ventilation system of a hospital operating theatre is designed to provide a comfortable andhealthy environment for the patient and the surgical team. A healthy environment can beachieved by minimizing the risk of contamination through an appropriate filtration and airdistribution scheme. The design and construction of operating theatres in Hong Kong,including the upgrading of the older ones, are based on the UK Health Building Notes andHealth Technical Memoranda. Observations and field measurements in a case study foundthat the airflow and some design features did not comply with the specified requirements.CFD analysis was used to examine the significance.
