another bout of congestive heart failure

I worried about it for several days, and sure enough, my brother is dealing with another bout of congestive heart failure.  It is hard to tell with him because the standard test, to look at the ankles for swelling is difficult with him because his ankles and feet are so skinny and very distorted.  But his face looked pretty full and he was gurgling when he talked. 

At breakfast, I asked him when the last time he was weighed and he said last week, and then, after much prodding he told me he weighted 149 lbs.  He also said he had mentioned to the nurses that he was hoarse and asked if he should do something about it, and they told him he was ok.  (It needs to be noted that he often gets information like this very messed up and that you never know what he really weighs or what he said to someone or what they said back.)

I was going to let it go for another week, but I noticed he was a bit out of breath from getting back into the car, so when we got back to the nursing home, I asked the nurse to look at the record of his weights, and sure enough, he weighed 152 lbs on May 3.  They are definitely supposed to be doing something when he gets into the high 140's.  So I asked that he be weighed again and then I left, and told them I would call back later in the afternoon to get results.

Within 5 minutes they called back, said he weighed 155 lbs, had already spoken to the doctor, and were putting him on higher doses of Lasex.  I spoke of my concern that they need to keep a close eye on his blood pressure, because it has been know to drop precipitously from dehydration, and that he also starts fainting, and that I didn't want' him to start breaking bones, which has also happened.  The nurse seemed very understanding and assured me they would be taking his blood pressure more often.

I have to keep an eye on this, and it nagging at me.  He is supposed to be weighed so that they can catch the congestive heart failure before it gets to crisis stage, and what's the point if they ignore the signals?  It makes me feel like I can never go out of town for any extended period of time without worrying, and that's not right.
