Face Masks Unlikely to Cause Carbon Dioxide Poisoning

Face masks do not increase carbon dioxide poisoning, and they are key to preventing COVID-19 infection, reports a new study.

Face masks are unlikely to cause overexposure to carbon dioxide, even in patients with lung disease, reports a new study. The findings of the study are published in the journal Annals of the American Thoracic Society.

As several governments worldwide have made it compulsory to wear face masks during the coronavirus pandemic, the researchers, noted that some people were discouraging its use, alleging it may be a health risk.

Wearing Facemasks Properly is Essential to Prevent COVID-19 Spread
Proper use of facemasks and facial coverings during the coronavirus pandemic is strongly recommended by experts to prevent the spread of COVID-19 infection.

‘During the COVID-19 pandemic, the wearing of face masks has become a highly political problem, with some individuals falsely claiming that wearing face masks may be putting people's health at risk. ’

The study assessed problems linked to changes in oxygen and carbon dioxide levels in healthy individuals and those with chronic obstructive pulmonary disease (COPD) before and while using surgical masks.

According to the experts, people with COPD "must work harder to breathe, which could lead to shortness of breath or feeling tired."

The effects are minimum at most even in people with very severe lung impairment," stated Michael Campos, the study's co-author.

Visualization Helps Test Facemasks and Social Distancing
Researchers have used flow visualization to qualitatively test facemasks and social distancing.

The feeling of breathlessness experienced by some healthy people while wearing masks is not synonymous with alterations in gas exchange. It likely happens from restriction of air flow with the mask in particular when higher ventilation is required (on exertion).

The solution is to slow down or remove the face mask if one is at a safe distance from other people.

Homemade Face Masks At least Need Two Layers to Restrict COVID-19 Spread
Homemade masks should have at least two layers, ideally, three to prevent the novel coronavirus spread, reports a new study.

More Use of Face Masks to Curb COVID-19
WHO advised people aged 60 years or over, or those with underlying conditions, to wear a medical mask in situations where physical distancing is not possible.
