"where are they going to put the “heart disease, cancer, unintentional injuries, CLRD, stroke, diabetes, alzheimer disease, liver disease and malpractice patients that ordinarily might need an ICU bed."
Anyone who isn't a) at deaths door b) treatable will be dumped for now I'm afraid. On your list I'd expect they'll only treat immediate cases of strokes, heart attacks, injuries. Alzheimers, cancer, diabetes etc will be classed as "non-urgent" and you'll just take your chances.
In Europe they're already cancelling chemo for example for long term cancer patients.
