Under what circumstances do medical masks need to be changed? Let's take a look at the small braid of medical protective masks

1. When respiratory impedance increased significantly;
2. When the mask is damaged or damaged;
3. When the mask can't close to your face;
4. When the mask is contaminated (for example, when there are blood stains or droplets and other related foreign bodies);
5. It has been applied to individual ward or patient contact (because the mask has been contaminated);
6. If the mask contains activated carbon, when there is a peculiar smell inside the mask.
In addition, the following points should be paid attention to when wearing medical masks:
1. Wash hands before wearing the mask, or avoid touching the inner side of the mask with hands during the process of wearing the mask, so as to reduce the possibility of contamination of the mask.
2. It is necessary to distinguish the inside and outside of the mask, the top and bottom. The light color side is the inside, and it should be close to your mouth and nose, with the dark side facing out. The end of the metal strip is the top of the mask.
3. Do not use your hand to squeeze the mask, including N95 mask. You can only isolate the virus on the surface of your mask. If you use your hand to squeeze the mask, the virus will be soaked through the mask with droplets, there is still a certain chance of infection.
4. Make sure that the mask and face have a good fit as far as possible. The simple test method is actually: after wearing the mask, exhale hard, the air can not leak from the edge of the mask.
