It keeps the surgical team from breathing into an open surgical wound. They have two pair of strings, one goes behind the neck tied in a bow, the other goes above the ears around the head tied in a bow.Does anybody kno what a surgical mask is used for and how do i wear one?the ones that needs to be tied.?
Sometimes cancer or AIDs patients wear them as getting even a small cold can be deadly to someone with those diseases. Also people who are sick or prone to sickness may wear them to prevent getting others sick or getting sicker.





They're pretty simple to wear, they have four strings. Two on each side top and bottom. Put it over your mouth and nose and tie the strings in the back like you would tie a bow in your shoe laces.
