Hi Carolyn, I am also a GB wife. My husband Bob who was 45 when he had a quick and severe onset of GBS(4 1/2 yrs. ago). He was on a ventalator for 8 mths. and they tryed to start weining him to soon. The muscles can’t still be paralized or it is only harder on the patient. Bob is breathing well on his own now but you have be patient. Once the lungs start working again they should get him to blow into an instrument that indicates how much strengh he has, when that gets to a certain level he can be taken off slowly, Bob had to have oxygen for a few months. It is such a slow recovery but have faith.
