My husband is in hospice for three weeks with CHF. His right leg is weeping, eyes half open/he is 6 2 , normally weighed 190, has lost a lot of weight. Sleeps sitting up, is on oxygen. He urinates alot, but does not drink much fluid. Has not eaten food for a weak. His eyes are yellow and large. Skin is a little yellow. Is he in the last stage of CHF?
