When providing oxygen to a patient with a suspected airborne infection, what should be applied?

In the context of providing oxygen to a patient with a suspected airborne infection, applying a surgical mask over the nasal cannula or non-rebreather mask is crucial to prevent the spread of infectious agents. Airborne infections are transmitted through respiratory droplets that may be released into the air when a person talks, coughs, or breathes. By placing a surgical mask over the delivery device, it acts as a barrier, significantly reducing the risk of airborne pathogens escaping into the environment and potentially infecting healthcare providers or other patients.

This practice aligns with infection control protocols, which are especially important in managing patients with suspected or confirmed airborne infections, such as tuberculosis or COVID-19. It helps ensure that patients can still receive necessary oxygen therapy while minimizing the risk of contagion.

The other options do not adequately address the need for infection control in this scenario. Not using a mask could increase the risk of transmitting the infection. A full-face mask without filters does not provide added protection against airborne pathogens, and a humidified oxygen system, while beneficial for patient comfort and respiratory function, does not contribute to infection control in the same way a surgical mask does.
