Hello sanjitkumar777 . i understand your father is currently in icu undergoing treatment for congestive heart failure
. It is a condition where the heart fails to pump blood efficiently ( hence the name heart failure ) increase volume of body fluids gets collected in the body itself in abdomen and lungs and lastly in blood vessels itself. Primary causes for congestive heart failure needs to be identified and then treated accordingly. Meanwhile if the primary cause could not be identified ( as in most of the cases ) , sypmtomatic treatment is given like restricting fluid intake , maintaining serum sodium levels draining out excess fluids from the as permissible and a proper antibiotic prophylaxis
if an infection is suspected . Most common cause of congestive heart failure is Ischaemic heart disease , Cigarette smoking
, Obesity , Diabetes ,Valvular heart disease
and there are other rare causes too. I firmly believe this kind of patients should be intesive monitering where they will get the best of attention and your father is in icu . Hope i have been able to clear your querries.
