B4.077 Cariopulmonary Disease in Geriatrics Flashcards
arteries
stiff
aorta
stiff
baroreceptor sensitivity
decreases; not as responsive
B-adrenergic response
decreases; not as responsive
left ventricle
stiff
atria
dilate
chest wall
stiff
joints don’t work as well
diaphragm
weakens
bronchi
stiff
alveoli
lose their elastic recoil
atelectasis
veins
stiff, valves don’t work as well
which type of heart failure is associated with aging?
diastolic
why does aortic stenosis occur with aging?
thickening and calcification of the valve leaflets
why do you have to be careful with BP management in older patients?
aorta is stiffer and less compliant
need higher pressure to get blood out
lowering BP too much could result in orthostatic hypotension
why does a-fib occur in older populations?
dilation of atria results in subsequent dilation of the conduction system
fewer pacer cells present
