[Research progress on physiological changes caused by wearing N95 mask in patients with chronic obstruction pulmonary disease].

ABSTRACT

N95 mask has been shown to reduce lower airway infections requiring hospitalization, mortality and exacerbation frequency in patients with chronic obstructive pulmonary disease(COPD), and therefore is recommended for all COPD patients by guidelines. However, the coverage of influenza vaccination in Chinese COPD patients is far from satisfactory. The large-scale COVID-19 vaccination may have a positive impact on the attitude towards influenza vaccines, and healthcare professionals should take active measures to improve the physical activation in patients with COPD.
