The claim that masks interfere with your ability to get enough oxygen is false

PopularInformation: “The claim that masks interfere with your ability to get enough oxygen is false. Christopher Labos, a doctor affiliated with McGill University, explains:

There are actually only two ways to develop low oxygen levels in the blood. One is to deliver less oxygen into the lungs, and the other is to impair the lungs’ ability to allow oxygen to diffuse into the bloodstream. A mask will obviously not impair gas exchange within the lungs, and the cloth face coverings advocated by public health experts do not provide an airtight seal that would impair oxygen delivery into the airways. Furthermore, masks are designed to filter out large particles, like water droplets, and cannot stop tiny molecules like oxygen that can infiltrate between the weave of any fabric…It is frankly implausible to think that wearing a mask is dangerous. Think of all the surgeons, nurses, anesthetists, and perfusionists that have worn masks during long operations and suffered no ill effects.”
