Procedural masks are breathable disposable masks designed for one-time use in medical environments and are traditionally characterized by an ear loop attachment and a coloured outer layer. They are used to protect both patients and staff from the transfer of respiratory droplets by coughing, sneezing or talking. Conversely, surgical masks are loose-fitting disposable masks designed for one-time use in medical environments. Intended for operating rooms, surgical masks are characterized by surgical ties behind the head and closeness of fit. They are designed to protect the clinician from contaminated fluid or debris generated during procedures.
