[|Human|] My father has severe CHF.  He is awaiting open heart surgery for two valve replacements.  Last night he was taken to er because he couldnt breath well due to fluid build up in his lungs.  He was bleeding form his mouth and nose.  They said he might not make it through the night.  But he did and is in critical care unit.  He is 74.  What does the bleeding indicate?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Bleeding from the nose and mouth in CHF (congestive heart failure) patient is mostly due worsening of pulmonary edema.CHF causes fluid accumulation in lungs. When this is severe, it can damage lung and cause bleeding from mouth and nose. So he should receive urgent treatment for pulmonary edema (diuretics and digoxin). Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
