Hey guys and welcome to the third episode of Physician

Assistant Boards.com Podcast and today we're gonna take a little time to

speak about CHF. Why do we care? It's the most common admitting hospital diagnosis.

550,000 new cases are diagnosed every year.

and are responsible for 11 million office visits yearly. Bottom line, CHF is very common, very important.

So let's take some time and let's go into a little bit more detail as to how exactly CHF occurs.

The first thing we'll start off with is how is the cardiovascular system supposed to work without any disease process.

We have deoxygenated blood, goes to the inferior vena cava, and the superior vena cava.

These two then dump into the right atrium.

Blood then goes past the tricuspid valve in the right ventricle.

Try right.

From there, it goes past the pulmonary valve into the pulmonary artery and into the lungs.

Here the blood is oxygenated and leaves through the pulmonary veins into the left atrium.

Blood will then pass through the mitral valve into the left ventricle.

Blood continues to make its way out past the aortic valve and into the aorta to profuse the rest of the body.

So the four valves to know.

Atrial ventricular, which makes up mitral and the tricuspid. Remember try, kind of sounds like right, so the tricuspid is on the right

side and the pulmonic and the aortic. When di when diastily occurs the heart will relax

the av valves will open

and blood will pass into the ventricles

the aortic and pulmonic valve are closed to prevent any type of backflow.

Then during systally, blood is ejected out into the past the pulmonic, past the aortic
