[|Human|] hi my friend is 86 years old with a defective heart valve.  they cannot operate as she would not survive the surgery.  her lungs fill up every month and she is in the hospital for this condition.  she goes to rehab and then goes home and back again with filled up lungs and shortness of breath.  your feeback please.  linda
[|AI|]  Hello, thanks for using Chat Doctor. I had gone through all the data posted. Lungs get filled up means that because of decrease in pumping action of heart blood gets pooled up in the lungs. When blood gets pooled up the water content of blood moves from blood vessels into lungs which causes shortness of breath. To tackle this we can do two things 1) improve heart function so that blood doesn't get pooled in lungs. 2) diuretic to decrease the water content of blood. So unless the heart function improves this cycle continues. Hope this helps.
