Flashcards in THINGS SHE STRESSED PT 1 -From Steve's Study Guide (Lectures 2/13 & 2/20) Deck (87)
the ability of blood vessels within organs to maintain a relatively constant blood flow regardless of changes in arterial pressure.
____ Blood pressure leads to stretch that results in constriction of arterioles and precapillary sphincters. _____BP results in vessel dilation in order to increase flow.
In the ______system obstruction manifests as distal ischemia in the _______system obstruction manifests as edema
__________ is a stationary blood clot formed within a vessel or a chamber of the heart. (pl thrombi)
Inflammation in vein –_______ and with a clot–_______
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
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
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 _____
IVC / SVC or Greenfield filter – used to prevent a _________
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.
insufficiency of the deep veins is _________.The legs become hyperpigmented, they swell, not enough flow in venous system
chronic venous insufficiency
Venous stasis ulcers will occur on the ________
cholesterol calcium plaques deposited in the arteries
___________weakening of the blood vessel where it pouches out. Predisposes to rupture and bleeding
___________abnormal communications between arteries and veins – most commonly found in brain and GI tract.
Arterial venous fistulas
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.
_______ 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
due to vasoconstriction or vasospasm. Interferes and blocks blood flow leading to color changes.
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.
More invasive, accurate diagnostic way to diagnoses PAD is _______ –when the vascular provider or cardiologist injects dye into the arterial system of lower extremities
Aneurysms: ______ increasing intracranial pressure, it might be hemorrhagic stroke. ______ sudden severe stabbing, tearing pain, radiates into back/abdomen, shock state
_______would have widening of pulse pressure 160 over 60
cerebral hemorrhagic stroke
_________-send a probe through the esophagus and take pictures of aorta via ultrasound most diagnostic and invasive for dissecting aneurysm
________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.
_______measures tissue profusion. Greater than ____ is considered tissue profusion. Surgeons can also put a graft in to repair.
________ absence of arterial circulation may result from thrombi, emboli, or mechanical compression
ACUTE ARTERIAL OCCLUSION
6 P's OF ACUTE ARTERIAL OCCLUSION
Pallor Paresthesia Paralysis Pain Polar Pulseless Pistol shot
Chronic venous insufficiency will lead to _____. They will have _________which will occur on the medial malleolus and pain.
edema; venous stasis ulcers
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.
