1

the ability of blood vessels within organs to maintain a relatively constant blood flow regardless of changes in arterial pressure.

auto regulation

2

____ Blood pressure leads to stretch that results in constriction of arterioles and precapillary sphincters. _____BP results in vessel dilation in order to increase flow.

high; low

3

In the ______system obstruction manifests as distal ischemia in the _______system obstruction manifests as edema

arterial; venous

4

__________ is a stationary blood clot formed within a vessel or a chamber of the heart. (pl thrombi)

thrombosis

5

Inflammation in vein –_______ and with a clot–_______

phlebitis; thrombophlebitis

6

During a thrombosis in the _____ system, patients will experience intermittent claudication, cool, cyanotic blue, painful ulcer in big toe. _______thrombosis – could be no s/s or could be life threatening (pulmonary embolism) calf/groin tenderness, swelling and Homan’s sign. Another way you can tell if a patient has a DVT is to do a _____. It’s not specific but it could start the work up for a PE

arterial; venous; d dimer

7

Embolis traveling to _____ventricle will go to the brain and will cause an ischemic stroke also known more specifically as an embolic stroke, that occludes a cerebral artery. An embolus leaving right ventricle gets into ______artery and causes a _____ embolis.

left; pulmonary 2x

8

Patients will present with sudden onset of SOB, Tachypnea, chest pain – this can cause sudden death, sometimes also back pain or scapular pain in a _____

pulmonary embolus

9

IVC / SVC or Greenfield filter – used to prevent a _________

pulmonary embolus

10

Clinical manifestations: often women more than men, organ specific – prinzmetal angina, in the brain can cause spasming and rupture of cerebral artery causing hemorrhagic stroke, migraine headaches would be another S/S.

vasospasm

11

insufficiency of the deep veins is _________.The legs become hyperpigmented, they swell, not enough flow in venous system

chronic venous insufficiency

12

Venous stasis ulcers will occur on the ________

medial malleolus

13

cholesterol calcium plaques deposited in the arteries

atherosclerosis

14

___________weakening of the blood vessel where it pouches out. Predisposes to rupture and bleeding

aneurysms

15

___________abnormal communications between arteries and veins – most commonly found in brain and GI tract.

Arterial venous fistulas

16

People who have atherosclerotic plaque do not just have it in one location they have it everywhere. They get ____ in the legs – stroke and CVA, myocardial infarction.

PAD

17

_______ studies these are both ultrasounds that use sound waves to determine whether there’s an obstruction). ________ test done to determine if a pt ankle systolic over brachial systolic. If less than _____ it’s considered PAD. Lower number lower the index more ____ PAD

Doppler/Duplex; Ankle Brachial Index; 0.9; severe

18

due to vasoconstriction or vasospasm. Interferes and blocks blood flow leading to color changes.

Raynaud's

19

CLINICALLY MANIFESTED as intermittent claudication. Lack of adequate perfusion to the legs – atrophy potential. Cool to touch extremities, weak or absent pulses, hair loss – the skin will look shiny.

PAD

20

More invasive, accurate diagnostic way to diagnoses PAD is _______ –when the vascular provider or cardiologist injects dye into the arterial system of lower extremities

ANGIOGRAPHY

21

Aneurysms: ______ increasing intracranial pressure, it might be hemorrhagic stroke. ______ sudden severe stabbing, tearing pain, radiates into back/abdomen, shock state

Cerebral; Aortic

22

_______would have widening of pulse pressure 160 over 60

cerebral hemorrhagic stroke

23

_________-send a probe through the esophagus and take pictures of aorta via ultrasound most diagnostic and invasive for dissecting aneurysm

TEE

24

________medical emergency treated medically with vasodilators it’s important to keep BP low – as low as possible to maintain perfusion, b/c the shearing force from the pressure will make the ripping of layers apart even worse.

Aortic aneurysm

25

_______measures tissue profusion. Greater than ____ is considered tissue profusion. Surgeons can also put a graft in to repair.

MAP; 70

26

________ absence of arterial circulation may result from thrombi, emboli, or mechanical compression

ACUTE ARTERIAL OCCLUSION

27

6 P's OF ACUTE ARTERIAL OCCLUSION

Pallor Paresthesia Paralysis Pain Polar Pulseless Pistol shot

28

Chronic venous insufficiency will lead to _____. They will have _________which will occur on the medial malleolus and pain.

edema; venous stasis ulcers

29

normal lymphatic flow is altered – usually secondary to mastectomy, radiation, or lymph node removal. You cannot draw blood or do blood pressures from this arm.

lymphedema

30

amount of blood ejected with each contraction of the ventricle. The amount of blood that is squeezed out of LV on systole.

Stroke volume
