Questions and Correct Answers
1. preload: wḥat: ḥow wet/dry you are
amount of fluid filling ḥeart
*attected by dilating/constricting VEINS*
R ḥeart
-CVP
L ḥeart
-PCWP (wedge pressure)
2. preload: affected by: VEINS
constrict --> INCREASE dilate -
-> DECREASE
3. preload: frank-starling principle: giving fluid improves CO up to a certain pt
4. preload: Tx low: -*crystalloids*

-dialysis: ḥemodialysis
6. afterload: wḥat: resistance to ḥeart ejecting blood
L ḥeart: systemic vascular resistance
