Which of the following statements is correct with respect to surgical masks?

All of the statements regarding surgical masks hold true, which is why the option indicating that "all of the above are correct" is accurate.

Surgical masks serve a crucial role in infection control within healthcare settings, particularly during clinical activities that may expose healthcare personnel to the risk of infectious agents through splash, spatter, spray, and aerosols. This is essential for providing a barrier to protect both the provider and the patient from contamination.

Moreover, surgical masks are classified as Class II medical devices, subject to strict regulations, including the requirement for performance labeling that aligns with standards set forth by organizations like the American Society for Testing and Materials (ASTM). This classification ensures that masks are evaluated for their safety and effectiveness before they can be used in a clinical environment.

Additionally, the mentioned performance characteristics of surgical masks—fluid resistance, bacterial filtration efficiency (BFE), particulate filtration efficiency (PFE), breathability (P-Δ), and flammability—are critical in determining their effectiveness. Each of these elements plays a vital role in the overall protective performance of the mask, ensuring that it meets the necessary standards for safety and efficacy during clinical procedures.

Since all these statements reflect accurate and relevant information about surgical masks, the selection indicating that all are
