Hospital HVAC systems play a critical role in mitigating the spread of diseases like COVID-19 (Coronavirus), MERS, SARS, and tuberculosis. It is recommended by ANSI/ASHRAE/ASHE and the CDC to place patients with a suspected or known COVID-19 diagnoses in an airborne isolation infection room (AIIR).
AIIRs are negative pressure isolation rooms with at least 6 air changes per hour (12 are recommended for renovations and new construction). Review our checklist to help insure your AIIRs are ready to receive patients.
For more details, refer to the ANSI/ASHRAE/ASHE Standard 170-2017 Ventilation of Health Care Facilities.
- Verify the room sensors are calibrated and working properly
- Verify room controllers and monitors are working and communicating with airflow valves
- Verify the room is operating at a negative pressure relative to surrounding areas
- Verify room pressure is being properly documented
- Verify correct air changes per hour are taking place per CDC/ASHRAE standards
- Verify temperature and humidity ranges are in place per CDC/ASHRAE standards
- Verify room air is being exhausted directly outside through a HEPA filter
- Verify doors are being kept closed except during healthcare personnel entry/exit
- Confirm patient rooms are visible on your BAS, for prompt notification of any issues
- Consider updating older VAV boxes to a fast-acting Venturi air valve or measured airflow valve
- Plan for an influx of patients and how to address isolation requirements in your facility
