Hemodynamics/Flow of Blood through the Body
Question | Answer |
---|---|
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 |
