Unit 4: Wk 13?? Flashcards
You designed an aerobic program for a pt taking a cardioselective beta blocker to control hypertension.
what is the function of this drug?
will the pt experience a training effect and undergo beneficial changes in CV system, or will the beta blocker prevent heart and vasculature from adapting?
Yes, CV function will still improve
- Function: suppress HR and decrease sympathetic nervous system activity
- it will decrease max hr but training effect will still occur w heart under control. It will also lower resting HR, improve vascular endothelial function, and reduce HTN as a result of aerobic training.
excessive renin angiotensin activity should be controlled because increased production of ___ causes ______________________
ang II causes vasoconstriction and vascular smooth muscle hypertrophy
nitrates such as nitroglycerine help decrease symptoms of angina because they _____ myocardial O2 demand by vasodilating the __________________
decrease O2 demand
vasodilate peripheral vasculature
myocarditis definiton, S & S, causes
ACUTE inflammatory disease of cardiac muscle
chest pain, palpitations, diffuse ST segment inversion
Causes: infection, toxins, radiation
cardiomyopathy definition
chronic disease of heart muscle caused by A degenerative condition
NOT ACUTE
WHAT ARE 3/4 OF THE CLASSIFICATIONS OF CARDIOMYOPATHY
dilation (most common), hypertrophic, restrictive
pericarditis
actue inflammation of the outer lining of the heart ; normally protects heart from rubbing mediastinum
pericardial effusion
accumulation of fluid within the pericardium; not usually life threatening
hemopericardium
blood accumulation in pericardium due to aortic rupture, traumatic perforation, ventricular rupture
*can cause cardiac tamponade
amyloidosis
abnormal protein thats produced in BONE MARROW that effects kidney, heart, liver, spleen, nerves
signs and symptoms of amylodosis
swelling, enlarged tongue , SOB, low BP, weight loss, purple around eyes
Sarcoidosis
systemic disease; formation of granulomas in lungs, eyes, skin
Sarcoidosis S & S
rash, nodules, fatigue, weight loss, SOB
OKT3
produces initial cytokine surge that makes pts feel very ill
fkr acute reactions
what are the two types of heart transplants?
Orthotopic heart
Heterotopic heart
types of lung transplants
what/who are they for
Single : pulmonary fibrosis, COPD
double : cf, bronchiectasis
heart lung: pulmonary htn, sarcoidosis, amyloidosis
living donor
endocardial biopsy
routine procedure to assess for rejection of heart transplant
reverse isolation requires what PPE
mask for you and pt, gloves, gown
signs of rejection
flu/fever
sudden decrease in exercise tolerance
SOB
chest congestion
who needs prehab
pts before they get transplants
what should RPE be for heart/lung transplants
12-14 (somewhat hard
IP goals for heart/lung transplants
independent, strength 3+/5, improved posture, independent in pulmonary hygiene
what should HR be below for heart/lung transplants
not to exceed 120 at rest
“heart rate inertia”
donors heart does not respond to owners nervous system
