WEEK 4 : Vascular disorders Flashcards
true or false. the concept of perfusion is cells receiving adequate oxygen and nutrients
true
what is this describing : ability to pump and how well that blood can mov into blood vessels
perfusion : blood pressure
which area does altered perfusion affect ?
low blood flow to a specific area or generally
sensation changes is one of the signs and symptoms : what undergoes this
numbness or pins and needles
ishcemic pain does not have to be in peripherally or centrally it can be chest pain as well with altered perfusion?
yes this is true
these are the diagnostics tests for altered perfusion: vascular problem
- EKG
- Blood work (enzyme rise)
- Angiography
- Ultrasound (doppler)
- CT scan
explain
ischemia to the heart
lack of oxygen release enzymes
tropinin is released from a cardiac muscle – patency blocked areas
can be deployed to open up
extremities to palpate a pulse
blood flow to the area to the body - angiogram is much better
when it comes to arterial occlusion:
limb is affected
what does pulse indicate?
if we cannot palpate ( act quickly )
pain because of ischemia
pulse indicate blood flow
abrupt occlusion is something we can deal quickly
quick symptoms
notify dr as soon as possible
are those true ?
what can obstruction be ?
can be blood clot, or fibrin, or narrowin
Medication to promote increased blood flow
* vasodilators, antihypertensives, diuretics
why are diuretics used ?
to remove excess fluid because of venous dysfunction
what is this describing : the disease is undetected for years -impedded the blood flow
and accelerating the plaque in the artery walls
hypertension
what could be a caused of hypertensive crisis?
diagnosed in hypertension but stopped taking medications
what does patients develop when they have htn crisis ?
cerebral edema
hypertensive crisis: severe headache, blurred vision, dizzy, SOB, epistaxis, anxiety , recall these are the symptoms
why are they experiencing sob
and epitaxis?
pressure gets very high in the lungs
tiny blod vessles get burst and then nose bleeds- epitaxis
often feel anxious when these symptoms are occuring
affected in lowering blood pressure
should not be dropped too quickly when it comes to hypertensive crisis
with hypertensive crisis - cerebral edema , why is this happening , and what would out intervention be ?
because of leakage
to reduce this - position in semi fowlers , less blood is flowing through their brain
ensure oxy sat is 92 is above
assess head to toe ( neuro done frequently )
ensure is producing adequate amount of urine
what is causing the cad
coronary artery disease
the diseae is caused by atheroclesoris causing it to narrow
can have a clot formed on top of the plaque and continuum in coronary artery
stable angina to mi
where does the symptoms typically occurs with pts who have cad /
majority happen in centralize chest pain
( chest pain that may radiate )
recall that these : * nausea & vomiting
* diaphoresis
* dyspnea
* anxiety/fatigue
often indicates disease progression
start with stable angina and cannot control indicate progressing partial or full occlusion
Coronary Artery Disease
Analyze Cues- ACS
Diagnostic Testing
- ECG
- Cardiac enzymes (Troponin)
- Coronary angiogram*
define the description for the diagnostic testing for cad
* ECG
* Cardiac enzymes (Troponin)
* Coronary angiogram*
changes in st segment
st elevation is infraction
depression is associate with ischemia and st elevation is associated with infraction
not receiving oxygenated blood
cardiac enzymes - whenever its damage. releases troponin - this support the diagnoses of mi
coronary angio - catheter for femoral artery in the groin or the wrist , threaded dye in injected radiologist and look at the big screen can see blood flow through the heart
Coronary Artery Disease
Plan and Prioritize-ACS
what is the worst thing that can happen?
complete occlusion of a cornary artrey
Any patient who presents with chest pain: with complete occlusion of a coronary artery
what type of diagnostic test are we doing ?
- ECG
- Cardiac enzymes
big priority :
competed occluded part of the heart muscle not receiving oxygenated blood
chest pain understand the severity - do ekg and cardiac enzymes 0 recognize quickly
just read
exemplar : #2 coronary artery disease
take acion - acs
intervention for acs
give a brief description on cad
myocardium not receiving adequate oxygenated blood
oxygen
ecg/cardiac monioring
pain assesmetn and management
frequent s
iv access
meds ( nitro, asa, clop)
why is cardiac monitoring important ?
is when myocardial developing dysrthmias
pain assesment what are we utilizing ?
opqrstuv
and pain scale ( nitroglycerin ) if not controlling might change in iv route in continous hepful in doesnt help in original
morphine could also be used, this causes vasodiliation
why should frequent vital signs be utilized ?
establish a baseline
not lowering bp, too much
nitro and morphine - cause low bp
