In which circumstances should you use a N95 respirator?

Using an N95 respirator is specifically indicated when caring for patients with suspected or confirmed airborne infections. This is because airborne pathogens can remain suspended in the air for extended periods and can be inhaled into the respiratory system, leading to infection. The N95 respirator is designed to filter out at least 95% of airborne particles, including those that are smaller than 0.3 microns, which encompasses a significant range of infectious agents, such as tuberculosis and certain viruses.

The use of this type of respirator is crucial in healthcare settings to protect both the healthcare worker and other patients from airborne transmission. This aligns with established infection control protocols that emphasize the need for adequate respiratory protection when dealing with highly transmissible respiratory illnesses. By using an N95 respirator in these circumstances, you significantly reduce the risk of inhaling infectious agents.
