get the patient up in a cardiac chair

Would you feel comfortable with this situation.

In the teaching hospital I work at there is a resident who insists that his patients get up in a cardiac chair (we have chair mode in the beds which can halt a person in a chair position)

-# 1 situation- Person post op day 2 from a basilar tip aneurism who is on a Nimbex/ cis. coma on PRVC with a ventric Otherwise regular IV fluids running no pressors no cooling issues. Bad idea because I feel she would just slide out especially with no muscle tone.

- #2 situation This patient had an aneurism rupture. Went for 5 days in a row with verapamil treatments, Keep SBP 160-180 on levophed to maintain the BP. Thiopental turned off two days ago and he still has thio in his system and stiff like a board. Pt has an uncontrolled high temp which he has a coolguard in place, scheduled tylenol, scheduled demerol to prevent shivering, and is sanwiched in cooling blanket (temp is still 38.0), has a ventric, has small bore feeding tube and is mechanically vented. I personally think there would be a line that would be pulled and it isn't a good idea.

-So what do you think of this situation?? Would you do it because I flat out refused.. Not out of laziness but because of patient saftey.
