A Guide to Fabric Changing
A surgical face mask, also called a full face mask, is designed to be worn by healthcare professionals during certain medical procedures to avoid airborne transmission of diseases in patients and/or the treating physician. It is recommended for those who have facial skin that is easily damaged. These masks are made out of sterile materials and used to cover the entire face with a thin layer of foam or neoprene. The mask is also airtight and prevents the spread of infections from one patient to another. It is used to protect the nose, mouth and eyes of the patient.
There are different types of facial masks for various purposes. General use face masks are for protection against irritants, allergens, and dust and are suitable for general or work-related exposure. Airway shields are used to protect the nose, mouth and eyes of the patients during surgeries. Specialty masks are used for facial trauma, burns, cuts and other conditions that limit the patient’s facial movements.
Full face masks are made up of an exhalation valve and nose clip. When full exhalation occurs, the air is blown out through a tube on the side of the mask. The full exhalation valve ensures that only air is taken in and out of the mask. Masks can be either open or closed; open masks are usually used during procedures when patients are awake and can keep their mouths closed while they undergo the procedure. Closed masks are used during sleep when patients can keep their mouths shut but cannot completely keep their noses shut.
Face coverings also come in many materials such as vinyl, latex, and plastics. Vinyl and latex are inexpensive and can be washed or wiped off easily with a wet towel. Plastic and prosthetic face coverings are expensive and must be replaced regularly. A plastic face mask usually comes with a battery-powered air pump that can be attached to the mask directly or be carried in a pocket to be pumped every time the wearer wants to clean their face coverings.
Face mask styles are limited to those that cover the entire head. Foil and snoode coverings are good alternatives to a full face mask, since they fit perfectly over the snout and nose. Snoode and foil coverings are very comfortable to wear because they have no wrinkles or lines on the skin. Both fabrics are good choices if the wearer has sensitive skin because both fabrics are hypoallergenic.
Some products contain a chemical called Covid-19, which makes it easier to remove the droplets. If you are using a face mask with the Covid-19 solution, you must pre-wash the fabric with cold water before use. This pre-washing gives the fabric a chance to absorb the solution before the wearer puts it on. If the droplets are already on your face, the fabric will not take in the solution well and could cause the fabric to turn dark. A darkening agent is used to make the liquid fall on the skin instead. This agent has to be pre-applied on the face mask before the application of the droplets.
