Nowadays, it is vital for hospitals to be prepared for future outbreaks of dangerous and infectious diseases, like Covid-19. For these situations, the safest method for treating patients is clean rooms. The safety and effectiveness of such rooms depend on proper control of the room's differential pressure.

1. What is hospital clean room?

A hospital cleanroom is a single room used to prevent contaminated particles from spreading beyond a quarantined area. To prevent particles from escaping, hospital clean room adopts negative pressure relative to the outside area.

Negative air pressure means clean air is drawn into the room and contaminated particles cannot leave. Instead of being recirculated through the main HVAC system, the air is then exhausted through dedicated ductwork and a HEPA filter.

Incorrect room pressurization can put patients and staff at risk of exposure if contaminants escape the space.

2. Maintaining the safety of hospital cleanroom

The most useful technique to implement a hospital clean room is to use room pressure monitor's (RPM) real-time monitoring and alarm capabilities. RPMs are the safest and most reliable monitoring solution for isolation rooms. Some RPMs even have the ability to monitor temperature and humidity.

A room pressure monitor produces both audible and visual alarms as well as connects to a building management system. When a room is compromised, the alarms sound, reducing the labor necessary to manually certify negative pressure. This minimizes the possibility of a catastrophic oversight.
