Week 7 - Hypertension Flashcards
1
Q
How does the sympathetic nervous system react to low BP?
A
- increases HR and arterial vasoconstriction
2
Q
How does RAAS react to low BP?
A
- increasing uptake of sodium and water (increases blood volume)
3
Q
When is ADH released in terms of perfusion?
A
- poor perfusion occurs in the body (increases volume and BP)
4
Q
What happens if BP is too high, after compensation? (2)
A
- ANP is released in the heart with increased preload in the heart
- it will increase sodium excretion and water loss
5
Q
How the body responds to BP diagrams (RAAS, baroreceptors, ADH)
A
6
Q
What is hypertension?
A
- sustained elevation of arterial blood pressure (have to determine if it is one time or overtime ie. white coat syndrome)

9

A
-1
- increases
10
Q
When can we diagnose HTN in terms of systolic and diastolic BP?`
A
- persistent elevation of SBP >- 140 mmHg
- persistent elevation of DBP >- 90 mmHg
