Our oxygen sats are fine, say mask-wearing docs
Doctors have taken to social media to dispel the myth that wearing a mask is dangerous, turning to their oximeters as proof.
Many doctors, health authorities and governments around the world are recommending masks be worn in public to reduce the spread of COVID-19.
But there is widespread resistance to the idea, especially in the US, with one key concern cited as being that wearing a mask causes hypoxia.
In response doctors have posted pictures of themselves on Twitter, wearing masks and displaying healthy oxygen readings.
