1. MAP, 65 - the average pressure the in arteries
- SBP + DBP (x2)/3
- should be >___________; less than that means poor perfusion
- used to help guide titration
2. Arteries - always have a pulse
- major control of arterial BP and distribution of blood
- readily respond to conditions (hypoxia, hypercapnia, etc.) by dilating or con-
stricting
- innermost layer is endothelium and is continuous with the heart
3. Capillaries - no ability to expand or contract
- site of nutrient, gas, and metabolic exchanges d/t thin walls
4. Veins - never have a pulse
- return blood to the heart
- larger veins have semilunar valves
- amount of blood in veins is changed by: arterial flow, compression of veins,
pressure changes between thorax and abdomen, and in the right atrium
5. Orthostatic BP 1. have pt lay flat for 2-15 minutes
2. take BP
3. have pt sit at edge of bed for 2 minutes
4. take BP
5. have pt stand for 2 mintues
6. take BP
- MAINTAIN SAFETY: if the pt is too dizzy to safely sit or stand, the number doesn't
matter. Report inability to finish taking BP to the Dr
6. 20, 10 if either the SBP or HR drops by _________ or the DBP drops by ________, the
pt is positive for orthostatic hypertension
7. Up BP should go ______ when a person stands

8. Preload stretch on the heart before it contracts
9. Contractility - the force with which the heart contracts
- ability to respond mechanically to an impulse
10. Afterload the force or resistance against which the heart pumps
11. HR, SV CO = ________ X _________
12. CO, SVR BP = _________ X ____________
13. SV ______________ is made up of preload, afterload, and contractility
14. HR, manually ALWAYS:
- check ___________ when taking a BP
- check the BP _______________ if it's too low
15. BP, HR the ANS, baroreceptors, and chemoreceptors regulate _________ and
___________
16. Baroreceptors cells that are sensitive to blood pressure changes
17. Chemoreceptors cells that are sensitive to chemical changes and balance (pH, O2, etc)
18. R. coronary - supplies that R. atrium, R. ventricle, and some of the posterior L. ventricle
artery - in 90% of people, it also supplies the AV node and bundle of HIS
19. R. marginal
artery

20. Posterior de-
scending artery
21. L. coronary - two branches: LAD and L. circumflex
artery - supply blood to L. atrium, L. ventricle, interventricular septum, and portion of R.
ventricle
22. L. circumflex
artery
23. LAD artery
24. L. marginal
artery
25. L. diagonal artery
