Video of Dilution and Pressurization

Ventilation plays many roles in health care facilities. Providing a comfortable environment probably comes to mind first. Behind the scenes, the ventilation system is important in preventing the spread of airborne contaminants and pathogens. As air is drawn into the return grills, it is either conditioned and filtered or is exhausted to the outside. Some percentage of fresh air is added, which is also conditioned and filtered. All of the air that is provided to a space by the HVAC system has been conditioned and filtered. Total air changes, outside air changes, system filters, temperature and humidity levels, and controlling the direction of airflow through the use of differential pressure for certain areas all play a role in providing an optimum patient care environment.
