A medical face mask, also called a nasal mask, is designed to be worn by healthcare professionals during various healthcare procedures. Nasal masks are designed to prevent infection in patients and saving staff from nose and throat irritation by capturing airborne bacteria and liquid droplets in the mouth and nose of the wearer. The membranes in a nasal mask are usually made from synthetic material, such as Lycra or Spandex, that allows airflow but keep mucus and other secretions from draining away. When a mask becomes full of bacteria or if it has become infected with bacteria, it must be removed immediately and replaced with a new one. Masks may also need to be periodically cleaned or sanitised to kill any bacteria or germs lingering on the surfaces of the mask.
The main advantage of using cloth face masks is that they are easy to wear and remove, making them suitable for use in all types of situations. These types of masks are especially popular in hospitals because they are used to cover the nose and mouth of patients who need immediate ventilation. Nurses and other healthcare professionals may also wear cloth face masks to prevent the spread of infections through their hands when they handle patients with serious conditions, such as those with pneumonia or serious allergies.
Another advantage of using medical or surgical masks is that they can help to stop the spread of infections that can occur through the air. The main reason these types of masks become contaminated is because they are used during procedures where the patient’s face, mouth or nose is open to the air. As air spreads across the patient’s face, the risk of spreading germs from one patient to another increases. For example, during a surgical procedure where an IV is inserted into the patient’s arm, if the IV bag gets contaminated with bacteria, it can spread potentially harmful germs to other people, including the surgeon and other healthcare workers.
Another benefit of using a face mask while doing surgery is that it will help to protect the skin around the surgical site from post-surgical contamination. If there is a contamination of any kind inside the mask, it could result in a reaction that could further compromise the work of the surgeon. If there is a leak or spill, it could get into the eyes and thus compromise the vision of the patient. Also, if the plastic covering over the nose and mouth gets wet, it could get into the nasal cavities and get into the throat, causing serious mucus irritation and discomfort. Finally, prolonged exposure to water or moisture could damage the sealing mechanism of the mask itself.
Some disadvantages of wearing face masks in general are that they will not provide a barrier against the spread of airborne diseases. This includes the transmission of airborne viruses such as colds and flu, as well as the transmission of airborne bacteria and germs, such as those found in the mouths of patients. Moreover, these masks will not prevent the spread of airborne irritants such as dust mites, which can cause very real reactions in the nose, throat and eyes of the wearer. The fact that the spread of pathogens is not always directly associated with the face-to-face contact with the infected person also makes face masks somewhat less useful than they could otherwise be.
It should be noted that a surgical face mask is generally a disposable item. While disposable face masks have been shown to reduce the spread of infections, they have also been shown to reduce the aesthetic quality of surgical patients. This is because the patient may not want to wear a face mask on a regular basis due to the problems it will create. In this case, if he or she were to continue to wear a respirator, he or she would be sacrificing the overall aesthetic quality of the surgical procedure.
