A surgical face mask, also called a full face mask, is designed for use by medical professionals during medical procedures. Surgical masks are designed to prevent infection in patients and limiting the transfer of bacteria from the patient’s mouth and nose to other handling staff and patients by capturing bacteria shed in mucus and mist droplets from the mouth and nose of the wearer. Face masks also protect the eyes of the medical professional from harmful infections and injury due to puncture wounds caused by sterile equipment or fluid spills. Face masks are usually worn by nurses, doctors, and midwives. The concept of face masking has spread into the emergency room as well, as these masks can also provide comfort and infection prevention to patients with facial injuries.
There are two common types of face mask – the nose mask and the full face mask. The nose mask is worn on the outside of the nose, near the tip. It is meant to cover the nasal passage while preventing any foreign objects, such as bacteria, from entering the nose. The full face mask is designed to cover the entire face, nose and mouth. It is designed to be worn under a helmet to protect the eyes from any mist or infection that may arise.
Masks have several benefits aside from infection prevention and visual comfort. These include protection against irritants, dust, and heat. They also allow better air circulation around the wearer’s head and neck, which is beneficial to the health of the person wearing it. Face cloth masks are considered more comfortable than face masks made from plastic and foam.
Aside from the infection prevention and protection, a good face mask should be easy to clean and maintain. It should be able to withstand high-pressure and high humidity, and should be able to provide a good air flow. For these reasons, most masks made from soft but synthetic fabrics are preferred. Some materials commonly used for face masks include cotton, polyester, spandex, nylon, and vinyl. These materials allow air to circulate easily and they are durable enough to make them resistant to sweat and water.
A surgical mask may also prevent dust and other allergens from entering the nose. It may also prevent small particles from entering into the nose, thus facilitating a more comfortable breathing process. These small particles are usually trapped within the mucous membrane that lines the nose and throat. However, some mucous membranes are quite thin, which means they may not be able to trap all the particles in the air.
One important benefit of wearing a face mask is noise reduction. Research has shown that wearing such devices can decrease the sounds heard by people who wear them by almost 40%. This is because these devices filter out small particles that may cause discomfort such as sawdust or dust. Since they also filter out large volumes of air, these masks also help prevent the irritation of people’s throats that can result from heavy breathing. Because they are inexpensive and do not have adverse side effects, they are popular choices for many people who need to wear headgear.
