Masks Recommendation for Pulm Patients

A note about mask-wearing for patients with lung disease: If you have severe lung disease, such as COPD or asthma, we still recommend you wear a face covering. It has been reported that masks do not allow you take in enough oxygen, or that they increase CO2 levels, but there is no medical evidence to support these claims.
