worried girl,
Sorry that you have to endure this pain, and make such a hard desision, I can tell you first hand about a trech..
I used to take care of an elderly gentleman who had one, and they can get plugged so easily with muscus and blood, and then that makes them almost smother if you dont get it suctioned out, it is to hard for an ill person to do this themselves... 911 was called several times because his was plugged and he couldnt breath, that is when i took it upon myself to go over there 4-5 times a day/night and suction it out, becasue he lived by himself and had no family close--- so having one of those she will have to be around someone constantly that can help her do that.. also sometimes it is very hard to just suction out, it is not a good thing.. so hopefully you dont have to go that route, but if you do you sound like a strong person and will be able to get through it.... also to let you know.. to me it does NOT sound like you are giving up on your mom, you just want what is best for her--- I am sure almost everyone one would chose not to stay alive by a machine, no quality of life.... Sometimes I think the quality is better then the quanity.... take care, thinking of you !
