[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Respiratory failure causes right sided heart damage and failure. Right side of heart receives blood from the body. So when it fails, venous return is hampered and so fluid accumulates in gravity dependent parts like legs. So this is the reason for swollen feet. So she will need higher dose of Las ix and additional diuretic (spironolactone). Fluid restriction (less than 1.5 liters per day) and salt restriction are also advisable. Limb elevation in bed also helps in the regressing edema. Hope I have solved your query. I will be happy to help you further. Wishing good health to your mother. Thanks.
