My 76 y.o. Dad has been in ICU since May 20, he was intubated until June 12 when they did a tracheotomy. He's been sedated, sort of awake (opening his eyes, moving his limbs, but not following commands), he's fighting pneumonia in his right lung, and has COPD. The pneumonia is getting better but his upper right love is still white on the xray. I'm concerned why he still isn't 'with it'. When they reduce the sedation, they say he gets too anxious, they've been giving him Xanax. Has anyone ever have issues with an ICU patient not following commands? They did a CT scan on his brain and there is no issue. Thank you.
