The correct way to wear N95 mask


Director Liang Jiansheng reminded that if people go to public places and do not come into contact with patients, it is enough to wear medical surgical masks, without overprotection, but if they come into contact with patients, they must wear biologically resistant N95 masks.

N95 masks are tightly protected, but there will be a clear sense of sulking after wearing for a long time. Wang Yuedan, a professor of immunology at the Peking University School of Basic Medicine, reminded that wearing a N95 mask should not exceed 4 hours at a time. If you use the N95 mask for a long time, it will cause lung damage and may cause problems such as emphysema.

Zong Zhiyong and Wang Yantong, experts in the Department of Infection Management of West China Hospital of Sichuan University, recommend not to wear N95 masks for children under 7 years of age, even if they are made with special air valve designs, because the respiratory resistance will be too large, and children will suffocate risk.
