Face masks unlikely to cause over-exposure to CO2, even in patients with lung disease

New Delhi, Oct 03 (ANI): New research findings contradict statements linking wearing face masks to carbon dioxide poisoning by trapping CO2. During the COVID-19 pandemic, the wearing of face masks has become a highly political issue with some individuals falsely claiming that wearing face masks may be putting people's health at risk. The study published in the Annals of the American Thoracic Society shows otherwise. In "Effect of Face Masks on Gas Exchange in Healthy Persons and Patients with COPD," Michael Campos, MD and co-authors assessed problems with gas exchange, that is, changes in oxygen level or carbon dioxide levels in healthy individuals as well as veterans with chronic obstructive pulmonary disease or copd before and while using surgical masks.
