My friend was on a ventilator for 3 weeks, asked his brother could they switch it off as they said they have done as much as they could do, brother said no, was moved to another hospital where they performed a tracheotomy so they could try him off the ventilator and he woke up a day or so later, he panicked because he couldn't talk or see so was sedated, got a phone call saying his heart is struggling and now might not even make the next 24 hours :( anyone who says covid is just a cold needs to know this is dangerous. I hope your uncle pulls through x
