1 A Cardiac

What changes occur with innocent murmurs? disappears with sitting no associated signs of cardiac dysfunction.
What is the pressure in the vena cava? 8-10
What is the pressure in the right atrium? 0-8 zero at first and then 8 when filled.
What is the pressure in the right ventricle? 0-8 to 15-25 it gets to 15-25 to pump up and out into the pulmonary circuit to the lungs to get oxygen.
What is the pressure in the pulmonary trunk through the pulmonary arteries to the lungs? 8-15 to 15-25 (there is no zero here, this starts at 8 which must be the pressure of the blood flow before the ventricle pumps blood here and increases the pressure)
What is the pressure in the left atria? 4-12 (this is blood coming back from the lungs-pulmonary circuit so it has to be lower than the 15-25 that was needed to pump it into the pulmonary circuit.)
What is the pressure in the left ventricle? 4-12 to 110-130 (4-12 is the pressure coming from the pulmonary circuit and 110 to 130
What is the pressure in the aorta? 110-130 over 70-80 ( this is systolic over diastolic blood pressure)
