Q
Compensatory Mechanisms
-Frank-Startling Mechanism
A
- Works in Preload.
2. The More you put in, the more the stretch, the stronger the contraction.
9
Q
Compensatory Mechanisms
-Neuro-Endocrine Responses
A
- When Frank-startling mechanism fails the BNP and ANP release
- sympathetic response with release of epinephrine and norepinephrine
- RAAS system
10

A
- Decreased HR and BP
2. Give Dopamine IV
11
