systemic tx -- cardiovascular treatment & pregnancy Flashcards
(206 cards)
atherosclerosis symptoms when?
likely no symptoms present until the vessel is blocked or narrowed enough to alter blood flow or thrombus/embolism formation.
atherosclerosis @ coronary arteries
Arteries in the heart may cause angina or heart attack. Symptoms: chest pain, difficulty breathing, restlessness, dizziness, anxiety.
atherosclerosis @ carotid? arteries
Arteries that supply head/brain, may experience TIA or stroke if embolism occurs (weakness, numbness, slurred speech).
peripheral arteries?
Arteries in the arms/legs patient may experience pain in arms or legs and intermittent claudication (peripheral vascular disease)
aneurysm
If vessel walls become weakened, aneurysms may occur – potential to rupture vessel, excessive bleeding and potential organ damage or fatal. Sudden severe pain in head or abdomen (brain, aorta)
CO
SV x HR
BP
CO x TPR
TPR
Size of the lumen of the vessel (vessel diameter)
Blood vessel length
Blood viscosity
normal BP
less than 130 systolic
less than 85 diastolic
prehypertension (high normal)
130-139 systolic
85-89 diastolic
stage 1 (mild) hypertension
140-159 systolic
90-99 diastolic
stage 2 (moderate) hypertension
160-179 systolic
100-109 diastolic
stage 3 (severe) hypertension
180-209 systolic
110 diastolic
stage 4 (extreme) hypertension
210+ systolic
120+ diastolic
hypertension symptoms when?
Asymptomatic until complications develop
May Be Variable depending on blood vessels affected
Possible dizziness, light-headedness, HA, fatigue, facial flushing and personality changes can all occur
Possible edema in lower extremities
primary vs secondary hypertension
secondary = Secondary to other condition-cancer, kidney disease, pregnancy, thyroid/sudden severe onset.
clinical manifestations, history
Fatigue/laboured breathing
Headache during exercise
Intermittent claudication
Chest pain
History of heart attack/heart disease
other factors
Client unwilling to make changes to health
Unknown health status
Congestive heart failure (need to speak with Dr)
when refer to doctor?
Undiagnosed hypertension
Stage 3 or 4 hypertension: wait 10-15 minutes and retake BP reading, (unless patient is displaying symptoms such as headache, anxiety, nosebleed-then immediate Dr. referral.)
—>
If still elevated on the second measurement, refer for immediate medical attention, especially if the diastolic is over 120
when 911?
**Call 911 if patient is experiencing shortness of breath, chest pain, difficulty speaking, etc
hypertension risk factors
Age
—> Anyone over the age of 45
—> Over half the population over 65 has some degree of hypertension
Family history
Diabetes
Obesity
Lifestyle
—> Smoking/diet/stress/sedentary
if new client presents hypertension risk factors?
**If new client presents with risk factors, take BP reading before tx
precaution, CI – CVD (“central”)
DON’T increase the work of the heart:
e.g. by dramatically increasing venous return
DON’T increase the risk of local tissue damage:
e.g. XFF can cause prolonged bleeding in malnourished tissue
DON’T interact with the use of medications: e.g. vasodilators and hydrotherapy
DON’T increase the risk of a secondary systemic complication: e.g. dislodging a thrombus
precaution/CI
tranverse/SEGMENTAL strokes to avoid increasing venous return
no intense techniques (e.g. frictions)
avoid cold hydro if an area is meant to be vasodilated
avoid deep comp to prevent “dislodging” thrombus
