What is a characteristic of a negative pressure room in a Sterile Compounding Environment?

A negative pressure room in a sterile compounding environment is characterized by having lower air pressure than the surrounding areas. This setup is essential for controlling the movement of air, ensuring that any contaminants from the compounding area do not escape into adjacent spaces. By maintaining a pressure that is lower than that of the outside or surrounding areas, the airflow is directed inward, effectively containing any hazardous substances or particles.

This is particularly important in the context of compounding environments, where the possibility of contamination must be minimized. Negative pressure rooms are often used to protect the environment and personnel in situations where compounding hazardous drugs is taking place, preventing any airborne contaminants from spreading beyond the designated area.

Other characteristics, like positive air pressure drafting, enhanced ventilation, or increased air quality, describe different types of environments and their controls, but they do not apply to negative pressure rooms specifically. Positive air pressure rooms could actually push particles outwards rather than contain them, which is counter to the goal of maintaining a controlled environment in sterile compounding areas.
