Doctor in Ireland wears six facemasks with no impact on oxygen levels

Posts video after questions from patients

A doctor in Ireland, tired of hearing people say masks will restrict their breathing, posted a video on Twitter in which he puts on six masks.

He does this while hooked up to a machine that measures oxygen levels in the blood.

The meter barely moves.

The U.S. Centers for Disease Control has said while carbon dioxide can collect between a person’s face and mask, it won’t collect in dangerous amounts or cause oxygen deprivation.

There is anecdotal evidence wearing a face-covering during exercise or prolonged periods of exertion can impact a person’s quality of breathing, depending on the type of mask worn.
