My Question Involves "Re-breathing Expelled Carbon Dioxide" as with a Particle or Surgical Mask. I have COPD!?

Surgical masks are dangerous and should not be worn. Carbon Dioxide (CO2) displaces air. It's commonly used to dispatch (kill) rodents humanely.
CO2 is also a carbon by-product. The body exhales CO2 as toxic waste after it has completed the metabolic process.

you would not be wearing one as doctors have adviced against it
