Positive Pressure Protects the Patient
The 4 ‘P’s mnemonic to help remember how and why it is utilised.
Positive pressure is often associated with operating rooms, where it is used universally to protect patients being operated upon from airborne pathogens entering the room via the airborne route. It is also now being used in minor operating environments and some outpatient type areas for the same reason, particularly around particularly vulnerable patients, who may be significantly immune compromised.
