Case Study: Negative Pressure in Dental Offices


October 15, 2020

The dental industry is currently one of the most at-risk industries during the COVID-19 pandemic. Since dental procedures create significant aerosolized particles, the risk for contracting COVID-19 or other airborne diseases is high, and thus many dentists are looking for ways to make their offices safer for patients and staff. DCAA Dental was searching for a simple, accurate, economical, and highly visible method to visualize whether or not a room was safely negatively pressurized.

Recently, the facility incorporated negative pressure into their patient treatment rooms for the sake of both patient and staff safety. Negative pressure rooms are designed to ensure the space contains any potentially contaminated air within the room, and exhausts this air as quickly as possible and as safely as possible. The end goal being to prevent any potentially contaminated air within the treatment room from spreading outside of the immediate space. A negative pressure space requires precise monitoring, especially of differential pressure; without monitoring, it is impossible to ensure the space remains appropriately negative, and thus safe for patients and staff.

To monitor the differential pressure of these new negative spaces, the facility chose the Setra Lite due to the Lite’s ease of use, simple installation, affordable price, industry-leading accuracy, and clear visual status indication. One of the first adopters of negative pressure technology in dental patient rooms within the US, the facility installed Setra Lite outside each negatively pressurized room. DCAA Dental can now quickly, accurately, and continuously visually monitor the pressurized status of each critical treatment space, alerting them whenever each space is safe to conduct high-risk patient procedures.
