CLEVELAND, Ohio - Researchers at University Hospitals Rainbow Babies & Children s Hospital (UH Rainbow) published new findings today that wearing a face mask - either a cloth mask or a surgical mask - did not impair the ability of subjects to get air in and out of their bodies.
The study measured heart rate, transcutaneous carbon dioxide tension, and oxygen levels in 50 adult volunteers at the conclusion of six 10-minute phases: Sitting quietly and then walking briskly without a mask; sitting quietly and then walking briskly while wearing a cloth mask; and sitting quietly and then walking briskly while wearing a surgical mask. The median age of participation was 33 years and 32 percent of participants indicated they have a chronic health condition such as asthma.
