In medical settings, a positive pressure room (protective environment) allows staff to keep vulnerable patients safe from infections and disease. in contrast, a negative pressure room uses lower air pressure to allow outside air into the segregated environment. this traps and keeps potentially harmful particles within the negative pressure room. Recirculation of air through hepa filters helps control the movement of airborne contaminants. a self closing entryway with adequate sealing prevents air from escaping. thoroughly sealed floors, ceilings, walls, and windows also play a role in helping maintain a positive pressure environment. fans and ductwork move air in the desired direction.
Positive air pressure: forces air out of the cleanroom. negative air pressure: draws air into the cleanroom. positive air pressure: stops contaminants from entering the space. negative air pressure: keeps contaminants from leaving the space. positive pressure rooms require high quality air filtration systems. Positive pressure rooms require at least 12 air changes every hour. they must maintain a minimum positive pressure differential of 0.01’’. if anterooms are used, the airflow must travel to the anteroom from the patient room and then into the adjacent corridor. normally, a 150 to 200 cfm airflow difference is sufficient for maintaining the. This positive pressure ensures that in the event of a breach or leak in the cleanroom, the products and processes within the cleanroom are protected. because the cleanroom has positive pressure, the air is forced out of the cleanroom, preventing contaminated or unfiltered air from seeping in. to achieve negative air pressure, external exhausts. The main difference between a positive pressure cleanroom and a negative pressure cleanroom lies in the direction of airflow. positive pressure cleanrooms maintain higher pressure inside compared to the surrounding areas, preventing the entry of contaminants, while negative pressure cleanrooms maintain lower pressure to contain hazardous.

In healthcare settings, isolation rooms have negative pressure, a positive pressure, or a switchable airflow. experts continuously debate the efficacy of positive and negative pressure isolation rooms and how airborne infection isolation room pressures should be managed. higher air pressures are positive, and lower air pressures are negative. Because the cleanroom has positive pressure, the air is forced out of the cleanroom, preventing contaminated or unfiltered air from seeping in. to achieve negative air pressure, external exhausts pull air from the cleanroom at a faster rate than air is introduced over a span of time. the resulting negative pressure means the air will want to.
