What PPE is required before entering a room for Airborne Precautions?

In the context of Airborne Precautions, the use of an N95 particulate respirator mask is essential because it is specifically designed to filter out airborne particles, including pathogens that are smaller than 5 micrometers. These airborne pathogens can remain suspended in the air for extended periods and can be inhaled by healthcare workers or visitors. The N95 mask provides a higher level of filtration than a surgical mask, which is primarily intended to protect against droplet transmission rather than airborne transmission.

The N95 mask helps prevent the inhalation of infectious agents, which is crucial when dealing with diseases such as tuberculosis, measles, or COVID-19, where airborne transmission is a significant concern. This necessity for using an N95 respirator underscores the importance of proper personal protective equipment (PPE) in controlling infection and protecting healthcare workers as they interact with patients in environments where airborne pathogens are a risk.
