We’ve covered a lot
of topics today.
But we should be able to
go back and think through
what an arterial to venous and
alveolar to arterial O2 gradient is.
You should also be able to describe
the different kinds of tissue hypoxia
and what are the mechanisms
underlying correcting that.
And remember that was a process
in which EPO was produced
and then produced more
erythrocytes or red blood cells.
You should also be able to predict
the mechanism of hypoxemia.
And you should go through a couple of clinical
scenarios that go through this process.
Remember the main mechanisms of hypoxemia
or hypoventilation or a low PIO2.
We have a diffusional impairment.
We have a right to left shunt
and a ventilation to perfusion
mismatch or inequality.
Finally, we went through the relationship between alveolar ventilation and hypercapnea
and if you have a hypercapnea, you’ll
know that alveolar ventilation was low.
If you have a hypocapnea,
you would automatically know that
alveolar ventilation rate was high.
