Exercise for Cardio/ Pulmonary Conditions Flashcards
Primary impairment in CAD
imbalance myocaridal oxygen supply n demand
narrowing due to
lumen of coronary artery
how does MI happen
blood to part of heart interrupted
most common cause of Mi (Heart attach)
occlusion (blockage) following by rupture atherosclerotic plaque
atherosclerotic plaque
unstable collection of lipids and WBC in artery
LV functions impaired
SV, Q, 02 delivery, v02 peak, WR
V02 equation
QxC(a-v)D02
what part of equation does CAD effect
Q (HR x SV)
stroke volume
RER higher or lower in CAD
higher
Why RER higher in CAD
impaired 02 delivery
incase metabolic acidosis
T/F Ve / VCo2 ration normal at rest and during exercise in CAD
true
when does respiratory compensation for metabolic acidosis happen
heavy exercise
T/F At similar in health and CAD
yes
Above the ischemic threshold, what happened to Vco2
incase more steeply in CAD
onset of myocardial ischemia
Curvilinear HR response
02 pulse below predicted
Are CAD patients ventilatory limited
not usually
Cardiac rehab
resorting individual with cardiac problem to max activity compatible with heart
goals of cardiac rehab
limit psych effect decrease risk of sudden death control symptoms stabilize atherscleorsis ADL
components of cardiac rehab
lifestyle (PA, Ed, Weight, Smoking)
Psychosocial
long term management
Phases of cardiac rehab
1-4
phase 1 cardiac rehab
in patient period
phase 2 cardiac rehab
early post discharge
up to 12 weeks supervised exercise / education
phase 3 cardiac rehab
supervised out patient program
variable leng program
intermittent or no ECG monitoring
