Patient Evaluation

Hemodynamics/Flow of Blood through the Body

QuestionAnswer
Hemodynamics/ Blood Flow Through the Body #1 - beginning with the LEFT VENTRICLE. - blood pressure 120/0mmHg - blood leaves the heart through AORTIC VALVE - enters the systemic arterial system
Hemodynamics/ Blood Flow Through the Body #2 - the mean arterial pressure in SYSTEMIC ARTERIES= 90 120/80 - and decreases to 30 as it enters the capillaries
Hemodynamics/ Blood Flow Through the Body #3 - inside the capillary the pressure is now 20 -blood leaves to enters SYSTEMIC VEINS now is10
Hemodynamics/ Blood Flow Through the Body #4 - the systemic venous blood moves slowly back to right heart - as blood enter RIGHT ATRIA pressure is now 2-6 or 4-12 -
Hemodynamics/ Blood Flow Through the Body #5 - blood in the right atria passes TRICUSPID VALVE into RIGHT VENTRICLE - where BP is 25/0
Hemodynamics/ Blood Flow Through the Body #6 - from the right ventricle blood moves through PULMONIC VALVE into PULMONARY ARTERY - pressure is 25/8 Mean pressure = 14
Hemodynamics/ Blood Flow Through the Body #7 -from the pulmonary arteries blow now pass through the lungs where capillary pressure is 8-10 and to PULMONARY VEINS
Hemodynamics/ Blood Flow Through the Body #8 - pulmonary veins moves to the LEFT ATRIA - pressure has dropped to 2-6
Hemodynamics/ Blood Flow Through the Body #9 - from left atria the blood passes MITRAL VALVE and into the LEFT VENTRICLE again.
Hemodynamics/ Blood Flow Through the Body #10/Cardiac Output - the output of the left ventricle is measured in L/min and is called CARDIAC OUTPUT.
Hemodynamics/ Blood Flow Through the Body #10/Cardiac Output/Normal Adult - cardiac output is 4-8L/min
Hemodynamics/ Blood Flow Through the Body Cardiac Index - is the cardiac output divided by the body surface area of the patient.
Hemodynamics/ Blood Flow Through the Body Cardiac Index/Normal - normal cardiac index = 2-4 L/min./m2
