Development of an empirical model to aid in designing airborne infection isolation rooms

Researchers from the National Institute for Occupational Safety and Health have evaluated the relationship between flow differential and pressure differential in 67 Airborne infection isolation rooms (AIIRs) and simulated AIRR. The date collected in the simulated AIRR allowed the development of an empirical model describing the relationship between the flow differential, the pressure differential and the leakage area. The data gathered in health care facilities proved the model predicted the leakage with accuracy . That model appears as an effective and cost-cutting tool.
