LH,
We had gotten a nurse for my dad that came in a few times a week and look after him, It was nice because a lot of times she could catch the pneumonia, before it got too bad and we could get him on the antibiotics before he got really critical. We would get him to ICU and then just wait.
My dad didn't want to be intibated, so when he did get it, we could nurse him through on a by-PAP, but the patients really hate it and he had to be sedated most of the time until the anitbiotics could work, but he beat it 4 times...pretty good for a COPD'er. The nurses and family would joke that my dad had nine lives, but everytime he went in, I would ask myself if 'this time' was going to be 'the time', and then eventually it was. I love him, miss him, but so glad he's not suffering.
He struggled too, he couldn't walk to the bathroom without gasping, and forget even trying to get him in the shower... the added heat and humidity made him so uncomfortable. Dad like it cold, even in the winter, he ran the air-conditioning...and we live in Ohio!!! lol If he would have tried to remain a bit more active, he may have gained some years, but when all your body can do is focus on breathing, it's hard to 'go for a walk', let alone eat, or have a lengthy conversation. Towards the end, we could have loud conversations around him, it would make him anxious and it would be harder for him to breath.
I know how much this hurts....my heart really goes out to you. I hate to see anyone else struggle and wish I could 'take this pain for you' Try to prepare, Can I ask if you've talked about a living will and life sustaining measures?? It's really hard to make all these decisions when they can't speak for themsevles and you and the rest of the family is emotional. I thought we had everything in order, but then there were some things we missed and Mom and I had to make some decisions, in the event he started to 'crash' in the night.
How are they treating your mother? What kind of treatments, how many liters of oxegen is she on now? IS her CHF being pretty well regulated or is she retaining a lot of fluids. The CHF can really compound her COPD ---the heart and lungs work as a team.
I may not have tons of advice, but I can tell you what I know. You seem to have a pretty good understanding of it, but I learned that the docs don't always tell you everything, or they try to handle people with 'kid gloves' I was lucky, I had some good nurses in my corner and they knew that I could digest the worst news. So I pretty much knew how it was going to finally happen, and what determines the end.
Above all, Try to take care of yourself, caregivers sometimes wind up sicker that the sick person. You will be no good to your mother, if your beat down and beat up. If you need to share, feel free. If you want to ask questions, ask me anything. If you don't want to talk about it, I understand that too. I'm here if you need anything.. anything at all (and I think it helps me heal too:unsure:)
