We have received numerous questions over the past few weeks about key components for an isolation room. This comes as no surprise since the world is currently battling the COVID-19 pandemic, which puts HVAC contractors close to the front line. Contractors are needed to help lead the charge in keeping hospitals safely up and running. This includes potentially converting unused dormitories and hotels into emergency hospitals for the overflow of patients that continues to grow every day.
The Centers for Disease Control recommends hospitals “prioritize AIIRs for patients undergoing aerosol-generating procedures.” AIIRs are, of course, Airborne Infection Isolation Rooms. The primary task for engineers and contractors is to create a negative pressure environment. (In the case of a converted space, there may be obstacles from the need to replace HVAC units entirely if they are not up to the task of maintaining safe ventilation.)
Negative pressure is required in isolation rooms because it prevents infected airborne particles from traveling outside the room. COVID-19 spreads through respiratory droplets. In this case, when doors to the isolation room are opened, the droplets will not spread beyond the room.
So, what components do you need? Room pressure will need to be monitored at all times.
- Room pressure monitors – Kele carries a variety of room pressure monitors from Setra, Johnson Controls, and Kele-branded.
- Pressure accessories – These may include pressure ports, probes, surge dampeners and more.
- Differential pressure transmitters are also worth noting for pressurization of an entire building, wings, and ducts. We wrote about this delicate balance here.
Call, email, or chat with Kele Technical Service if you have more questions about negative pressure and pressure monitoring in isolation rooms or other areas of a healthcare facility. And thank you to our customers and all contractors working to maintain safe treatment environments and keep critical infrastructure viable. Kele is open and here to support you. Stay well!
