This was known early on:
Severe #COVID19 patients are having trouble breathing because of lung airway stenosis.

This is why ventilators are needed.
To help people breathe.

The goal pharmaceutically is to reduce the swelling in the lung airway w/o damaing the lung OR heart. https://twitter.com/boriquagato/status/1247252362701328384

The anti-viral #Hydroxychloroquine much like the antibiotic #Gatifloxacin (Tequin removed from market 2008) causes QTc interval prolongation,
which causes heart arrhythmia, which causes the heart to work harder, or strained cardiac output, weakening the heart.

People don't die from #COVID19, they die from complications or when their organs shut down. Lungs, kidneys & heart.

THIS is why it's dangerous for the public to know about #Hydroxychloroquine w/o understanding when it's used & why it needs studied.

#Zithromax or common branded #Zpak is an antibiotic that's been used in some COVID19 along w #Hydroxychloroquine to stave off secondary bacterial infections & help w the reduction of lung airway swelling.

There is a reason for FDA regulated pharmaceutical clinical trials.

The pharmaceutical solution or cure, should not create more problems for patients or healthcare providers.

While it seems logical to "try anything" against #COVID19 that flawed thinking could cause unnecessary predictable & predictable deaths.

If you are sick, see a provider.
