Heart failure Flashcards
What is systolic dysfunction vs diastolic dysfunction
systolic cannot empty adequatelt
diastolic cannot fill adequately
what is the presentation of CHF
fluid around lungs, bloated stomach and swollen and cyanotic feet.
what is left-sided failure
cough, tachynea, sob, fatuge and exertional sob
what is right sided failure
weight gain, dependent edema, fatigue
what is paroxysmal nocturnal dyspnea
sob at night dt fluid shifting towards the heart
what are benefits of exercise for chf
decreased skeletal muscle inflammation and improves periphera blood flow
what are some special considerations
30 - 40% reduction in CO and TTE.
Cardioprotective meds decrease the ability for heart rate to ramp up
What are some CI to exercise for pt with CHF
worsening of condition, cannot maintain homeostasis, exercise is contraindication until medcically stable
what is post exercise hypotension
reduction in BP 5 - 20 mmhg
When to stop exercising
exceed 200mmhg or drops greater than 10 mmhg
t/f low fitness level = less room for improvement
false
what are the overload ranges for cardiac patients
40 - 70%
FITT principle for cardiac patients
F - daily
I - stepwise increase (plateau before progressing)
T - 10 - 15 mins a day
T - functional and then specific
what are the differences between UE and LE exercises for heart failure patients
UE causes more vasalva because you need more o2 uptake than LE
What symptoms do you need to monitor for CAD and stop exercising
ANGINA
Acute coronary syndrome: injury and infarction
injry - new acute MI
infarction - non reversable
brings to a risk of heart failure
name some anginal symptoms
cest pain, syncope, sob, severe fatigue, nausea
What are signs and symptoms of decreased cardiac output.
severe fatigue and dizziness
pallor, dizziness, confusion, sob, tachycardia
what is considered orthostatic hypotension
decreased 20mmhg systolic, 10mmhg diastolic
what is exertional hypotension
bp decline with increasing workload
What is the management of orthostatic hypotension
isometric counterpressure manoeuvers.
induces blood pressure increase during symptoms
what are special considerations for patients with afib
rhythm irregularities
need to measure manually over a full minute due to irregular heartbeat
most are on anticoagulated meds due to stroke increase so they have an increase with beleeding
what are special considerations for diabetic patients
monitoring blood sugar
hypoglycemia
dont inject insulin to muscles that will be exercised
have snacks close
