Term
| What is the pulse pressure? |
|
Definition
The difference between the systolic pressure and diastolic pressure
|
|
|
Term
| What is the mean arterial blood pressure? How would you calculate it? |
|
Definition
The pressure that would exist in the artery if there were a steady flow of blood from the ventricle MABP = diastolic pressure + 1/3 pulse pressure |
|
|
Term
| Total peripheral resistance = |
|
Definition
| TPR = (Pa-Pv)/Cardiac Output |
|
|
Term
Vascular compliance = What are the characteristics of compliance? |
|
Definition
Compliance = Change in V / Transmural Pressure Compliance decreases with increasing pressure Compliance decreases with age |
|
|
Term
| What does the mean arterial pressure depend on? |
|
Definition
| Volume of blood in the arteries and the peripheral resistance |
|
|
Term
|
Definition
| Change in volume / compliance |
|
|
Term
| What is arterial volume increment? |
|
Definition
| The change in volume in the arteries during systole; its proportional to the stroke volume |
|
|
Term
| The mean arterial pressure increases proportional to to an increase in what? |
|
Definition
|
|
Term
| If you decrease compliance but hold volume constant, how does this effect systolic and diastolic pressures? |
|
Definition
| The systolic pressure rises to a higher level and diastolic pressure falls to a lower level |
|
|
Term
| As resistance increases, pressure also increases because __________. |
|
Definition
| of the increased volume on the aterial side of the circulation |
|
|
Term
| At high levels of resistance, how are pressure and compliance effected? |
|
Definition
| Pressure increases and compliance decreases |
