Influences on BP

Influences on Systolic & Diastolic Pressures

QuestionAnswer
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
