(2) ALVEOLAR VENTILATION lecture Flashcards
tidal volume?
insiratory resever volume ?
expiratory reserve volume?
residual volume ?
vital capacty
functinal residual capacity?
EXAM Know this one and caculate
tidal is the normal one
extra air is insiratory resever volume ( if you ihale more then you usually do)
expiratory reserve is when you exhale more then normal
residual volume cant be used , anything invulving this one cant be measured (can olny be measured threw dilation)
vital capacity is the sum of the all 3 not reidual volume
functinal residual capacity pervents you from turning blue when you exhaul
what happens to total lung capacity as you age
what happends to redisual volume?
what happens to volume of lungs
if you lose your aviula its called
compliance is a
total lung cacpacy decreases with age
after you exhaul it doesnt recoil as much as it use to
decreases with age
no avulia is called alelactasis
compliance is a change of volume is a change of pressure- only thing at increases- inhaling causes a pressure change- easier to do that as u age becuases elastisity decreases
how to increase compliance ?
lung elasticity
why do lungs become stifer with age?
what is recoil
lungs become easier to ________ btu do not ____ as readily
inflate
recoil
anything ventilation is what units
ML/min
its a rate term
what is dead space
ventilator that doenst go into the rest of the
dead space
physiological dead space
what is bohr method and is assumptions( equation in pic)
what is the equation? very important
if your ventilation goes up what happens to partial pressure?
part of the lung should take part in gas exchange
20%-30%
greater then atomical dead space
-uses partial
Va=VC02/PaCO2 (alveolar equation)
if your ventilation goes up/ partial will go down and vise versa
Vd = (cunducitng regions) no gas exchaneg
VT- toal
defin flower and borhn
ventalation is not equal.
lower zone is more ?
replanishm of air occure more?
lower ones get ?
lower zone is more ventualted then upper zone
replanishm of air occure more in the lower parts
expanded more
10min-26 in ventulation
