Just because your PCO2 is 97 does not give you the liberty to verbally assault and berate myself or my nurses because you want to lie flat and sleep.
The fact that you apparently don't care to live, yet still come to the ER so frequently is a mystery. We all know you're a jerk. Especially considering you smoke while on oxygen, refuse medications, and left AMA just last week for the same COPD exacerbation. That you refuse to cooperate in your own (lifesaving) medical care, with your RA sat of 80%, is a brilliant strategy. In fact, that Bipap you just tore off was your last chance. Cursing and screaming at the nurse was an bonus, and even though it made your bluish face turn red, it really didn't help your situation much. I'd love to just throw you out, but you do technically have a lifethreatening emergency.
Therefore, it gives me the right to declare you an idiot, "incapable of understanding the seriousness of your medical situation due to hypoxia and hypercapnia," and go ninja on your airway.
(Fearing he'd get violent, we all massed outside the room while a different nurse pushed the etomidate. Then rushed, tubed, tied down, propofoled, and suggested strongly to the admitting doc that they keep him intubated as long as they planned to keep him in the hospital.)
That would be my tax dollars saving you, buddy. Groan.
