I don't know if this helps at all, but I have been in ICU at Good Samaritan in Phoenix, and I hope you will feel free to continue to fight the ICU docs and insist that they let the CF docs have the ultimate say. If there is a way they can try slowly weaning him off the vent to see if he is able to begin rebounding, that would be best. I had a nightmare of a time with some of the ICU staff at Good Sam, but fortunately my CF docs listened the first time I complained (in writing on the notebook I had beside my bed, since I obviously couldn't talk) and they adamantly took over all the decision making. I was successfully weaned off the vent, but I don't know if I was as sick as your brother so I don't want to give you any false hope. I was an the vent for about 6 days, and was sedated throughout. Still, I wasn't incoherent, so it makes me mad that they act as though your brother is too out of it to make decisions.
I am so sorry for you to be carrying this heavy load. It is impossible to know exactly what to do, and it is impossible to really know if the ICU docs may be right anyway. But at least they should treat you with absolute respect and be willing to try everything without pressuring you into giving up.
One thing I would like to say to you from the perspective of being a CF patient. I knew that my husband was doing everything he could to try to keep my best interests at heart. Your brother knows how much you love him and how hard you are fighting for him. If I had died, I would never in a million years have wanted my husband to have felt he let me down in any way. I promise you, your brother feels the same way. He knows and is deeply comforted by your love and support. If for some reason he does not do well, please do not beat yourself up for not doing enough. CF is ultimately way more powerful than all of our intentions. Love alone cannot cure CF. Even powerful medications and technology cannot yet win the battle. Please know in your heart that your brother feels the power of your love. You are an awesome sister.
If there is any way I can help, please let me know. I work very near Good Sam, have lots of contacts in the medical world in Phoenix because of my job, and I will do whatever I can to get you information or advice. You can e-mail me at asiansoccer21@cox.net if you'd prefer to contact me personally.
I will keep you and your brother in my thoughts and prayers.
