“Wearing an N95 mask for 4 hours during HD [hemodialysis] significantly reduced PaO2 and increased respiratory adverse effects in ESRD [end-stage renal disease] patients.”
Granted, the participants in this study were very ill. But the results underscore the fact that universal mask wearing can be dangerous for some, and possibly for many, people.
Most of the relevant results from the studies cited above are related to the N95 mask, currently the best mask for protection from viruses. The various types of cloth masks now regularly recommended and frequently used perform much worse.
Now, even the CDC itself has admitted that wearing cloth masks of the type it recommends for COVID are not effective for small particles. On August 30, the CDC posted a warning on this point to Facebook related to smoke.
“Cloth masks that are used to slow the spread of COVID-19 offer little protection against wildfire smoke,” the CDC said. “They do not catch small particles found in wildfire smoke that can harm your health.”
Writing for RedState, Scott Hounsell makes several good points about this CDC admission:
“Remember that ‘science’ that they always like to throw in the face of conservatives?” Hounsel writes. “Let’s take a quick look at this info through the lens of actual science. They just told us that smoke particulates are too small to be stopped by a cloth mask. While N95 masks will protect up to 95% of particles, down to .1 microns in size. A quick Google search will tell us that smoke particles and debris are usually .4 to .7 microns in size. According to the CDC, cloth masks are not effective in stopping materials that size.”
Another quick Google search will tell us that the Wuhan Virus is .12 microns in size, about a quarter in size of the smoke and fire debris particulate. Even if we factor for the “respiratory droplets” that are allegedly to blame for the spread of coronavirus, those droplets are as small as .5 microns, or as small or smaller than smoke and fire debris particulate. These factors and figures aren’t hidden in some CDC vault that only their scientists are capable of accessing. Yet another quick Google search will show these figures within seconds.
The CDC cannot, on one hand, demand we wear masks because of the prevention of the spread of a disease (or droplets containing the disease) and then tell us that those same masks are ineffective in stopping particles that are bigger than the disease we are trying to prevent.
In the end, people who wish to wear masks of whatever type should feel free to do so. But mandates as favored by Democrat and RINO politicians are inappropriate and ineffective, as the CDC is now more or less admitting.
