AV fistula:
Preload: {{c1::Increased::Increased/Decreased}}
Afterload: {{c1::Decreased::Increased/Decreased}}
CO: {{c1::Increased::Increased/Decreased}}
Extra
Due to the fistula:
- Blood can bypass the high resistance of the systemic arterioles → SVR is effectively decreased → decreased afterload
- Blood returns to the right atrium more quickly and easily → increase in venous return → increased preload
- Decreased SVR requires a compensatory increase in CO to maintain organ perfusion (MAP = CO × SVR), increased venous return contributes to the increase in CO
