Cardiopulmonary Failure

Question 1

heart failure

Answer 1

inability of the heart to provide adequate cardiac output
doesn't mean total failure
can be caused by
--muscle (myocardial)
--valve (mechanical)
--afterload (circulatory)
ALWAYS forward and backward failure

Question 2

pulmonary valve stenosis

Answer 2

forward failure from RV on, backward failure fromRV and before
not as much blood getting through the valve into the pulmonary artery
lungs and Left heart itself is not affected, but volume of blood will decrease going to the periphery
