In addition to standard PPE, what extra gear is necessary before entering a room with airborne precautions?

When dealing with airborne precautions, the use of an N95 respirator is essential due to its ability to filter out airborne particles, including viruses and bacteria that are transmitted via respiratory droplets smaller than 5 microns. Unlike surgical masks, which primarily protect the patient from the wearer's potential contaminants, the N95 respirator is designed to provide a tighter fit around the face and filter at least 95% of these particles, significantly reducing the risk of inhalation of infectious agents present in the air.

The importance of this protective measure is highlighted in healthcare guidelines, which specify that airborne precautions are necessary when caring for patients with diseases such as tuberculosis or certain viral infections that can be transmitted through the air. The N95 respirator's design ensures that healthcare workers are protected while providing care, unlike standard surgical masks, which may not offer sufficient protection against small, aerosolized pathogens.
