Positive pressure rooms are used for immunocompromised persons (eg. Neutropenic) whereby controlled quality air is sent into the room to prevent random (and potentially polluted) air from entering the room. [4] The CDC recommends a positive pressure differential of at least 2.5 Pa between the positively pressured room and the adjoining hallway. [5]
A filtered air positive pressure environment in laboratory animal science is a space that is under positive pressure with respect to the outside world. In this way, no germs that could affect the lab animals or that are a threat to the SPF status can enter the facility. [1] To bring in new air, high efficiency particulate air filters are used.
A pressure room may refer to: A positive pressure enclosure, which uses positive pressure to remove harmful substances from the enclosure; A negative pressure room, ...
Schematic of a network of rooms where air (shown in blue) flows in one direction from the corridor into the negative pressure room (green). Exhaust air is safely removed from the area through a ventilation system. Negative pressure is generated and maintained in a room by a ventilation system that continually attempts to move air out of the ...
Continuous positive airway pressure (CPAP) is a form of positive airway pressure (PAP) ventilation in which a constant level of pressure greater than atmospheric pressure is continuously applied to the upper respiratory tract of a person.
Special equipment is used in the management of patients in the various forms of isolation. These most commonly include items of personal protective equipment (gowns, masks, and gloves) and engineering controls (positive pressure rooms, negative pressure rooms, laminar air flow equipment, and various mechanical and structural barriers).

The PPPS is a sophisticated variety of personal protective equipment (PPE), a type of hazmat suit, which is air-tight and designed for positive pressure to prevent contamination to the wearer even if the suit becomes damaged. BSL-4 cabinets and "Suit Laboratories" have special engineering and design features to prevent hazardous microorganisms ...
