Surgical face masks are essential. Masks are used to perform as barriers and provide better protection for patients and healthcare professionals. Tissue characteristics (weight, thickness, pore size, and resistance to synthetic blood penetration) are believed to influence barrier activity and evaluate the relationship between these characteristics and BFE. Two difficult microorganisms, Staphylococcus aureus, and Escherichia coli were studied in this study.
A protective face mask is a loose, practical device that creates a physical barrier between the nose and mouth and possible contaminants in the direct vicinity. Please note that the sides of the Mask are not designed to seal around the nose and mouth.
