Q

Airborne Precautions

A

(highest risk precaution)
Droplets smaller than 5 microns, remain in air for longer periods of time
*Private negative pressure room (suction effect - keeps all the bad air in)
Air is filtered thru high-efficiency particulate air (HEPA) *N95 respirator for personnel

Q

“Reverse” isolation - Protective Environment

A

Protects immunocompromised patients
