I feel for you, sounds like you had a very harsh day. I have worked Hospice for almost 2 years. I love it, it is my calling I do believe. But on a personal note, last year my mother in law passed away. She had E/S COPD, and emphysema. She too was on BiPap for about 48 hours, and it brought her sats up. She was on Hospice, and had it at home. The thing to remember is, when they are end stage, it is what it is. Bipap wasn't gonna save the pt, just make them a little more comfortable, and allow them a little more time, so they could say that last good bye. You stayed by their side, comforted them, fed them, and supported them. You did everything you could do, and then some. Even dealing with the NP, and that annoying beep.....Sometimes we just have to let off a little steam, and it just so happens that you waited til you got home to do it. I hope your next day at work isn't quite so hard.....God puts us in situations that he knows we can deal with. You're always where you are for reason... :)
