Sample questions:
1) what is joe’s resting VO2?
Heart rate= 70 bpm; [stroke volume]Q = 5 L/min; CaO2 – CVO2 = 5%
a) 0.25 L/min
b) 1.75 L/min
c) 2.5 L/min
d) 17.5 L/min
e) 25 L/min
*cardiac output= HR x SV
CO/ HR = SV
VO2 = HR x SV x (CaO2 – CVO2)
= Q x (CaO2 – CVO2)
= 5 L/min x 5%
VO2 = 0.25 L/min
2) what are cilia?
a) hair like projections in your nose, throat, trachea, and bronchus that capture debris in the air you breathe
b) hair like projections that r in your trachea and bronchi that capture debris in the air you breathe
c) it is the flap that keeps air out of your stomach and food out of your lungs
d) they are the rings in ur trachea that keep ur aiways open
3) what is NOT afeature of restrictive lung disease:?
a) decreased lung compliance [stiff lung]
b) vasoconstriction [narrowing] in some areas of the lungs
c) excessive mucus productions [this is more common in OBS ;obstructive lung disease]
d) increased respiratory rate [hard to expand the rib cage’ shallow rapid breaths]
e) all of these are features of restrictive lung disease
4) What causes Right ventricular heart failure in COPD?
a) insufficient blood flow to the heart
b) artherosclerosis
c) pulmonary hypertension [when muscles r hypoxic i.e. low oxygen, the blood vessels vasaldialate to allow more blood to the areas
to supply more oxygen to the hypoxic areas of the muscles. Exact opposite happens in lungs, cuz blood goes to lungs to get oxygenated

and if areas of lungs are lacking oxygen blood cannot b sent to those areas as it wont pick up any oxygen and vasal constriction
happens within the lung tissue and areas with low oxygen concentration to redirect the blood to the areas which r getting good oxygen
supply to get re-oxygenated. In people with lot of areas that lack oxygen get lot of vasal constriction..so much restricted that it becomes
hard to pump the blood thru small blood vessels. Pulmonary hyptertension works like a pump n makes your heart pump the blood a lot
harder.. which leads to right ventricular heart failure.]
d)rigid lung pressing on the heart
e)all of the above
Chronic Obstructive Pulmonary Disorder(COPD)
COPD = Bronchitis + Emphysema
-bronchitis ..inflammation of bronchioles.
-emphysema: destroying of alveolar walls (small alveoli walls are destroyed losing surface area making larger alveoli walls)
-hence don’t get much surface area for gas exchange to occur

Normally, hypoxia (low oxygen) in the muscle causes
vasodialation (vasal dialation of blood vessels)
Vasal dialation allows more blood flow and restore oxygen supply
(low areas of oxygen open up and lets blood in)
 blood flow
 oxygen supply
BUT….Hypoxia in pulmonary blood vessels
but in lungs the areas of low oxygen constrict and instead the
lungs send the blood to areas with high oxygen content and
then the blood gets picked up and goes to the rest of the
areas of the body tissues. if no air no blood can be picked up.
So The lungs send blood to only areas with high oxygen
content where the blood can actually be picked up
-vasoconstriction too much contriction leads to ->
pulmonary hypertension heart is trying to pressure the
blood from right side; low areas of oxygen. Lot of strain on
heart and the load will cause right ventricle heart failure.
afterload causes right ventricle heart failure
COPD is –ive to you because Can cause Right Ventricle Heart
Failure
-right side of heart pumps blood to ur
lungs
