1. 3 factors that control the bp
• heart
• blood
• vessels
2. the pump that creates the bp
heart
3. amt of fluid in the circulatory system will affect the bp
blood
4. inc in the hr/strength will
inc bp
5. dec in the hr/strength will
dec bp
6. excessive fluids will
inc pressure
7. loss of fluids will
dec press
8. vessel constriction will
inc press
9. vessel dilation will
dec pressure
10. systolic, diastolic and mean arterial pressures MAP are monitored continously by using a
indewelling arterial catheter with a pressure transducer
11. normal pressure for systolic
120 mm hg
12. normal pressure for diastolic
80 mm hg
13. normal pressure for mean
93 mm hg
14. mean arterial pressure MAP formula
MAP= (2 x diastolic) + systolic / 3

normal value in the teens
15. right heart problem
CVP
16. lung problem
PAP
17. left heart problem
PCWP
18. normal ranges for CVP
• 2-6 mm hg
• 4-12 cmh20
19. normal ranges for PAP
25/8
20. normal ranges for PCWP
4-12 mm hg
4-8 l/min
22. normal cardiac index
2-4 l/min
23. monitor does not show the normal dicrotic notch and the catheter is somehow obstructed
pressure dampeninge
24. increase CVP =
• right heart failure
• cor pulmonale
• tricuspid valve stenosis
25. increase PAP =
• lung disorders
• pulm embolism
• pulm htn
• air embolism
26. increase PCWP/ decrease Qt
• left heart failure
• miltral valve stenosis
• CHF
• hih peep effects
27. to get rid of fluid, you give
diuretic
28. the difference btwn the systolic and diastolic pressure
pulse pressure
29. formula for pulse pressure
sustolic pressure - diastolic
30. normal value for pulse pressure
40 mm hg
31. measures the output of the left ventricle to the systemic arterial circulation
cardiac output
32. stroke vol equation
heart rate x stroke vol
33. cardiac output formula
qt/ bsa (body surface area)
34. pressure gradient across the systemic circulation divided by the cardiac output
systemic vascular resistance SVR
35. SVR formula
(MAP - CVP) / cardiac output
36. normal value of SVR
< 20 mm hg/l/min or 1600 dynes
37. to conver mm hg/l to dynes,
multiply by 80
38. pressure gradient across the pulm circulation divided by cardiac output
pulm vascular resistance PVR
39. PVR formula
(MAP - PCWP) / cardiac output
40. normal value of PVR
< 2.5 or 200 dynes
