What should be considered when evaluating ventilation in a critical space?
When evaluating ventilation in a critical space, keep in mind that the system should be flexible enough to change the room environment as necessary to contain any potential spread of airborne infection. Recent studies indicate that up to one-third of all hospital-acquired infections are airborne. Airborne contaminants include inorganic particles, airborne mold, and bacteria. To improve ventilation and reduce the risk of airborne infection, consider the following:
- Air quality
- Filtration frequency of air exchanges
- Positive and negative air pressure
- Exhaust systems
