#COVID-19 #coronavirus FACT: The prolonged use of #medical masks* when properly worn, DOES NOT cause CO2 #intoxication nor #oxygen deficiency
The prolonged use of medical masks can be uncomfortable. However, it does not lead to CO2 intoxication nor oxygen deficiency. While wearing a medical mask, make sure it fits properly and that it is tight enough to allow you to breathe normally. Do not re-use a disposable mask and always change it as soon as it gets damp.
* Medical masks (also known as surgical masks) are flat or pleated; they are affixed to the head with straps or have ear loops.
