Influences on BP
Influences on Systolic & Diastolic Pressures
Question | 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 |
