Ventilators do not ‘purify’ air. Ventilators are designed to help remove Carbon Dioxide from the bloodstream by enhancing compromised Respiratory Systems. Ventilation is the Number 1 life function. If we do not ventilate, we die, period.
It is not even about Oxygen. You can inhale 100% O2 and die if you are unable to ventilate.
My sister died from that at end of this january.
I now keep thinking she might have had this virus and disease.
She donated her body to science, so I wonder how to know for sure.
just an FYI...I talked to my sister’s daughter.
My sister had gotten bad the last year.
She couldn’t exhale carbon dioxide. her lungs were like “raisins”?
She wasn’t about to keep going back to the hospital to get ventilated.
When she did pass, with her last breath, it appears she more or less drown.
So this wasn’t related to COVID-19.
