Hello
Your father is suffering from congestive heart failure( CHF ).
With mild to moderate CHF, the heart is not as powerful as it once was. As less blood is pumped out of the heart with each beat, the blood returning to the heart through the veins backs up. This back-up causes fluid congestion in the tissues. When that congestion occurs in the lungs, the person experiences
shortness of breath.
This is the reason your father is having fluid in lungs and abdomen and there is congestion in
liver.
20% pumping action means
ejection fraction is very low.
Normal range of ejection fraction is 50 to 75 %.
lower the Ejection Fraction number,Higher the Risk.
Ejection fraction, or EF, is the percentage of blood that is pumped out of the heart during each beat. Doctors often use EF to determine how healthy your heart is and how well it is functioning as a pump.
Your EF number is a key indicator of your heart health.
A low EF number is a serious health risk. If you’re a heart patient with an EF of 35 or below, you’re at significantly higher risk of sudden
cardiac arrest (SCA).
Since the EF is 20%,your father is at great risk and should be hospitalised.
Treatment required is to remove the fluids and increase the contractile power of heart with help of medications.
Let the doctors assess and treat him and so it should be left on them.
Thanks
