|---|---|---|---|---|---|
| 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

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
