You could try doing what I did after waiting for a solid 2 hour for the nurse to return to intubate me after surgery after ringing for them for another hour I got up unplugged my monitor and pulled out the tube down my throat and used the can , while a crash team of 10 finally arrived only after there alarm went off lol when you got to go you got to go . Though being a dumb ass is not always a good thing, get well soon and to a speedy recovery for you sir . At least if your able to complain your alive and that is a good thing everything else is secondary .
