(HealthDay): Carbon dioxide levels among children wearing masks may exceed healthy limits, according to a research letter published online June 30 in JAMA Pediatrics.
Harald Walach, Ph.D., of the University of Medical Sciences in Poznan, Poland, and colleagues assessed whether the covers of the nose and mouth increase carbon dioxide in the inhaled air. The analysis included 45 children (mean age, 10.7 years) who tested two types of nasal and buccal covers (a surgical mask and a facial face filter mask 2) in a laboratory-like environment.
The researchers found that levels were similar between the masks, with averages ranging from 13,120 to 13,910 ppm of carbon dioxide. Only age was associated with the carbon dioxide content in the inhaled air. He the little ones had the highest values of carbon dioxide, with carbon dioxide level measured up to 25,000 ppm. The 0.2 percent volume (2,000 ppm) limit was more than three times exceeded among children with lower carbon dioxide levels.
“We suggest you decision makers weigh the obvious evidence produced by these experimental measures accordingly, suggesting that children should not be forced to carry facial masks“, write the authors.
