Answer |
| What is the definition of Systolic BP? |
the pressure which develops during the contraction of the contraction of the LEFT Ventricle |
| What are the 3 influences of Systolic BP? |
1. Stroke Volume (Contractility); 2. HR; 3. Arterial COMPLIANCE |
| How does Stroke Volume influence Systolic BP? |
INCREASE Stroke Volume --> INCREASE Systolic Pressure |
| What is the differnce between Compliance and Elasticity? |
Compliance: ability to STRETCH; Elasticity: ability to squeeze back (recoil) |
| What effect would an increase in HR have on BP? |
INCREASE HR --> INCREASE Systolic BP |
| What effect would a decrease in Arterial Compliance have on BP? |
DECREASE Compliancy --> INCREASE Systolic Pressure |
| What effect would a decrease in Elasticity have on BP? |
DECREASE Elasticity --> DECREASE Diastolic BP |
| What effect would an increase in HR and Contractility have on BP? |
INCREASE HR --> INCREASE Diastolic BP |
| What effect would and increase in Peripheral Resistance have on BP? |
INCREASE PR --> INCREASE Diastolic BPE PR --> |
| What is the definition of Peripheral Resistance? |
the resistance within the Arteriole Network |
