How often should a surgical mask be changed?

A surgical mask should be changed after every patient to ensure optimal infection control practices. This is because surgical masks are designed to protect healthcare workers and patients from the transmission of microorganisms during medical procedures. Over time, masks can become damp from exhaled moisture, reducing their effectiveness. Additionally, they can collect pathogens, which can then be transferred if the mask is not replaced frequently.

Changing the mask after each patient also adheres to the principles of standard precautions and ensures that there is minimal risk of cross-contamination during clinical activities. This practice is particularly important in settings where sterile techniques are employed, such as in surgeries or procedures that might involve exposure to bodily fluids. Regular replacement maintains a higher level of safety for both providers and patients.
