When the overseas epidemic is still severe, how can we protect ourselves and choose suitable masks?

Disposable medical mask: daily use. The bacterial filtration efficienc. y (BFE) of disposable medical masks is ≥95%, and the ventilation resistance should not be greater than 49Pa/cm2. This type of mask is suitable for ordinary people to use when they are not in contact with patients with fever, cough and other symptoms. Generally, it is enough to wear it when going out or taking public transportation.

KN95 mask: available for short-term contact with patients. Filter elements of filter-type respiratory protective equipment are classified into KN and KP according to their filtering performance. For microorganisms, just look for KN, the number "95" refers to the level of filtration efficiency. KN masks only test the filtration efficiency of particulates, and dose not test the synthetic blood penetration, surface moisture resistance and other indicators. This type of mask can block the virus when used for a short time, but it cannot be used to contact patients who may be splashed or contact patients for a long time. It can be used by ordinary people and medical personnel who have been in contact with patients with new coronary pneumonia for a short time, but cannot be used by professionals who have been in contact with patients for a long time. In addition, the N95 mask is a mask that meets American standards. Chinese medical protective masks are a type of N95 masks, but not all N95 masks are medical protective masks.
 

Disposable children's mask: change every day. In general, it is enough that to change the disposable masks once a day. Choose the appropriate size of mask for children. The specifications are large (L), medium (M), and small (S). When wearing the mask,teach the child to press the metal strips on both sides of the nose bridge with both hands when wearing the mask, so that the upper end of the mask is close to the bridge of the nose, and stretch the mask downward without wrinkles.


Choosing the right, suitable mask is also a kind of protection for ourselves.
