Respirators used in healthcare are traditionally a specific variant called a surgical respirator, which is both approved by NIOSH as a respirator and cleared by the Food and Drug Administration as a medical device similar to a surgical mask.[18] These may also be labeled "Surgical N95", "medical respirators," or "healthcare respirators".[19][20] As part of the Families First Coronavirus Response Act, changes were made to liability and certification laws to allow industrial respirators to be used in healthcare settings, in response to shortages of respirators during the COVID-19 pandemic.[21]
