That assumes all COVID complications are caused by low O2, which is not the case.
I do agree “with COVID” is an improper metric.
I believe that if looking at “COVID hospitalizations”, the metric should be “COVID as a significant contributing factor to admission”. VERY often, and this has not really changed, admissions are due to combinations of factors. I saw it repeatedly with both my Mom and my Dad.
Regardless, the bottom line is whether or not a hospital has proper care capacity for additional incoming patients, and if not, is such care nearby.
If we just had a chart of supplemental O2/ventilators over time, we’d know if the ‘hospital overloading” was due to COVID or the vaccine mandates firing staff.
I don’t think we know, and our media might not tell us, even if they know.
