| 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) |
