My father and mother both had COPD, and I can attest that it is not unusual for a person having a COPD exacerbation that requires them to go to hospital to require 4 litres per minute of oxygen. My mother died before this pandemic garbage, and my father died from aspiration pneumonia months after the peak of it and never was diagnosed with covid. Both of them had multiple exacerbations before they died, as well as episodes of pneumonia, so I have had plenty of experience with this to know what I'm talking about. The nurse doesn't know what she's talking about. It's quite obvious now that doctors, nurses, and politicians are obsessed with covid to the point that they can't reason anymore.
