Ok so : They were both in a facility (nursing home/rehab) in Charlotte NC where my brother lives. My mom was in the rehab getting over radiation so she could go home to die as she wished. She was fine no problems we were all looking forward to seeing her and helping her make her life choice (end stage lung cancer) then BAM 4 days later she was dead. My mom died in Early March and there were zero COVID tests in the USA. Her death cert listed pneumonia, and something else (cannot remember) as #1 & 2 then 4th was lung cancer and where it said 'Did smoking impact the life' it was marked unknown (which was bullshit)
My dad was in the nursing home. 100% sure the staff gave him whatever it was , it was ruled COVID and confirmed with a test. Between the time my mom died and my dad we were in lockdown and I could not fly back to NC ( I live in Nevada). So hell I really don't know as far as intubate but I'd guess no.
EDITED: wow way too much info sorry. TL;DR I don't think so.
