The Principles of Hemodynamics Explained Flashcards
Movement of blood and determines tissue perfusion, oxygen, and nutrient delivery.
Describe the term hemodynamics.
Movement of blood.
Explain the importance of hemodynamics.
Determines tissue perfusion, oxygen, and nutrient delivery.
List the four major chambers of the heart.
Right atrium, Right ventricle, Left atrium, Left ventricle.
Define the role of the atria in the heart.
Pumps and feeds blood into the ventricles.
What function does the ventricle serve in the heart?
Pumps blood into the vasculature.
How does blood flow from the right atrium?
To the right ventricle.
What is the role of monitoring techniques in hemodynamics?
To assess a patient’s hemodynamic status.
Define the goal of optimizing a patient’s hemodynamics.
Maximize blood flow throughout the body.
Identify the first chamber blood enters in the heart.
Right atrium.
Which valve does blood pass through from the right atrium to the right ventricle?
Tricuspid valve.
What valve does blood exit from the right ventricle?
Pulmonic valve.
Where does blood go after passing through the pulmonic valve?
To the pulmonary arteries.
Describe the next chamber after the lungs in the circulatory system.
Left atrium.
Explain the function of the mitral (bicuspid) valve.
It connects the left atrium to the left ventricle.
Identify the valve through which blood exits the left ventricle.
Aortic valve.
List the two largest veins that return blood to the heart.
Superior vena cava and inferior vena cava.
Define the function of the coronary sinus.
It returns blood from coronary vessels to the right atrium.
What type of blood is carried by the pulmonary arteries?
Deoxygenated blood.
How is oxygenated blood returned to the heart?
By the pulmonary veins.
Explain the acronym TPMA in relation to heart valves.
It stands for Tricuspid, Pulmonic, Mitral, Aortic.
Describe the pathway of blood after it leaves the right lung.
It goes to the left side of the heart.
What is ejected from the left ventricle during contraction?
Blood.
Through which valve does blood exit the left ventricle?
Aortic valve.
Identify the major artery that blood enters after passing through the aortic valve.
Aorta.
