Final Flashcards
1
Q
CV functions
A
- delivery of O2 and nutrients
- removal of waste products
- heat
- delivery of WBC
- hormone transport
2
Q
Tricuspid valve
A
-between left atria and ventricle
3
Q
Mitral valve
A
-between right atria and ventricle
4
Q
Ejection Fraction equation
A
- (EDV-ESV)/EDV
- normal is 55% or higher
5
Q
Cardiac output determinants
A
- preload
- afterload
- contractility
- HR
6
Q
BP equation
A
-TPR x HR x SV
7
Q
CAD
A
progressive disease of arteries supplying O2 and nutrients to heart muscle
-lipid deposits in layer of medium and large coronary arteries
8
Q
CAD risk factors
A
- blood lipid levels
- obesity
- diabetes
- hypertension
- tobacco
- high fat diet
- physical inactivity
- age
- gender
- family history
9
Q
PVD
A
-any disorder of circulation of the extremities
-acute= embolus
chronic = PAD
10
Q
PAD-
A
most common in superficial femoral and popliteal arteries
- intermittent claudication can progress to gangrene
- treatment=exercise, meds, surgery
11
Q
Concerns of venous insufficiency
A
- edema
- decreased tissue nutrition/necrosis
- skin atrophy
- stasis promotes thrombus formation
12
Q
Anti-arrhythmic (amiodarone)
A
- used for afib, vtach, vfib
- prolongs repolarization phase of cardiac action potential
- can cause bradycardia and m. weakness
13
Q
Ca channel blockers (meds)
A
- Amlodipine
- Diltiazem
- Nifedipine
- Verapamil
14
Q
Ca channel blockers info
A
- treat hypertension/angina/afib
- vasodilator by relaxing smooth muscle to decrease peripheral vascular resistance to reduce BP, increasing BF to heart
- causes peripheral edema, dizziness, fatigue
15
Q
Beta blockers meds
A
- Atenolol
- carvedilol
- metoprolol
