positive pressure
Higher than ambient
Positive pressure refers to air or fluid pressure higher than the surrounding environment.
In ventilation systems, positive pressure pushes air into a space, preventing outside contaminants from entering: The clean room maintains positive pressure.
In medicine, positive pressure ventilation forces air into the lungs rather than relying on natural breathing.
The opposite is negative pressure, which pulls rather than pushes.
