crslkwd,
Dr. B is pushing holistic medicine which has no scientific backing.
He has many such ridiculous treatment regiments.
There are many alternative providers with many alternative claims and made up treatment regiments.
There are a number of patients that have tried this treatment that you have listed and ended up on a ventilator.
There are a number of treatment options for patients that are having respiratory symptoms. Including nebulizers (beta-agonists and steroids).
What I would say in a public forum, the hospitals are fully capable of handling COVID patients, they are not above capacity and some have good treatment protocols, with teams of providers that have enormous experience treating COVID patients.
There has been a lot of positive feedback from recent patients that were admitted. Depending on where you live, I would suggest that if you have problems with your breathing or your primary care provider believes that you should go to the hospital. Rather go earlier than later. There are a number of treatments that are shown to be successful in helping patients recover sooner which means less negative effects on the body.
