I have no idea what the treatment protocol is for COVID-19, but, I was looking at a scan posted online in a news article. It was a 3-D image of the lungs that rotated. The shaded areas were active virus and lung inflammation. Now, while something needs to be decided about ending the virility of the virus, there is something that can be done about the inflammation. I am thinking of the people in critical care and those not in critical care but in hospital beds and those in some areas of the country on homecare.
Inflammation is a defense mechanism of the lungs. But, in cases of asthma, it can also be part of the problem because the mucous can become thick rather than watery and actually block available lung space. That is why during an asthma attack a person needs to cough and deep breathe, which is counter-intuitive. Not the cough, but, the deep breathing.
If patients, especially those on vents are having inflammation, then they could be experiencing higher than normal antibodies, but, also a higher degree of mucous production. To inject or give intravenously any systemic steroids would in all likelihood suppress the immune response, but, if a critically ill patient is provided nebulizer treatments of medication like Pulmicort it would act in time to reduce the inflammation. In reducing the inflammation a physician could be providing more alveolar space, hence, more oxygen to the body.
My other thought is to have a back up to Zithromax. It is believed that Zithromax and Chloroquine are treatments, but, a patient's reaction to antibiotics may be questionable. I simply thought a back up of a broadspectrum antibiotic that also assists the kidneys and the ear infections these folks complain about would be a good alternative.
That is my two cents after seeing that video online in a news article.
