A surgical face mask, sometimes called a facial mask, is designed to be worn by medical personnel during medical procedures in order to avoid airborne transmission of diseases in the patient and/or the treating physician. Face masks are used during surgical procedures for several reasons, the most important of which is to limit the transmission of infections from the patient to the doctor or other medical personnel involved in the procedure. Infections can also occur in the operating room due to improper hand washing after the surgical procedure. When using a surgical mask during a surgical procedure, one should remember that they should not be used on patients who are unhygienic or have an increased risk of contracting infections. If infection does take place during the procedure, the doctor may offer to wash his hands prior to beginning the procedure and use disposable plastic gloves to protect his hands.
A surgical face mask comes in two different types: a cloth mask and an airtight plastic mask (or dc). The first type of mask has a chin strap that attaches to the face, preventing any leaks onto the patient’s face. The second type does not have a chin strap but rather a neck strap that attaches to the neck of the patient. C dc masks typically have some type of nose piece attached to the nasal mask. These particular masks have small holes at the top that allow the air to flow through them.
In addition to having a seal, a cdc face mask must also have some type of ventilation system included in the mask. Most cdc masks have a tube or hose at the top, which is attached to the mask’s chin strap. This tube or hose can be adjusted in order to provide increased or decreased air flow. Some cdc masks require that the mask be washed before each use in order to remove any residual soap or other cleaning agent. If this is the case, it is important to thoroughly rinse the mouthpiece out prior to using it the next time.
Another common feature of a surgical mask is its ability to contain aerosols. Surgical masks are often made of special fabrics that contain fine particles of foam that are injected into patients’ nostrils. These tiny aerosols can cause immediate irritation if a patient’s nasal cavity is sensitive, or they can cause a reaction in sensitive individuals. An aerosol can be contained in the nose tray, worn as a cuff on the face, or positioned inside the mask itself.
In addition to being able to contain aerosols, a face mask may also be used as an air purifier. In a recent study by the Royal Society of Medicine, a surgical mask was found to reduce the number and size of bacteria that were present in the patient’s nose. The majority of these bacteria were a group called Streptococcus-capitis. Although the sample size of this group of bacteria was small, this study supports the theory that the cdc can be used to significantly reduce the bacterial count in a patient’s nose.
Surgical masks may also reduce the level of irritants in the air. A medical study published in JAMA indicates that surgical masks may reduce the number of dust particles inhaled by the general public. In previous research, the same group of scientists indicated that a high percentage of the general public suffers from allergies. They determined that the majority of these allergy sufferers were located in the household of individuals with children who lived in houses built with carpets or who had pets with a significant amount of dust mites in the house. Individuals exposed to large amounts of airborne dirt are more at risk for allergies.
