short for Intensive Care Unit.

ICU is a place in a hospital where they place a person who's in very critical condition so he/she can be closely monitored, and if necessary p0laced in care. They have care from the least critical like people who had a heart attack, and are breathing, and are fine, but need to be monitored closely, to the sickest of the sickest patients who require complete bodily functional support from a ventilator, ECMO, and lots of other machines.
1. He's in ICU, and they have him on the jet ventilator.
2. What's going on with him?
3. He's probably not going to survive. He's in severe ARDS.

IcU means "I'm cool, you?". It is sometimes used in chatrooms for typing faster.
