I understand the idea to let him sleep it off. That’s what I’d do, but then I’m not a medical professional who’s had proper medical procedure and triage of patients drilled into me over the years. That’s why we go to hospitals, because they’re supposed to know better.
Very sad. But he was that sedated, in our country (for now, anyway), he should have at least been in the ICU, perhaps even on a ventilator to protect his airway.
