Learning Outcomes – Hypoxemia and Hypercapnia

00:00 Great! We’ve covered a lot of topics today.

00:05 But we should be able to go back and think through what an arterial to venous and alveolar to arterial O2 gradient is.

00:16 You should also be able to describe the different kinds of tissue hypoxia and what are the mechanisms underlying correcting that.

00:25 And remember that was a process in which EPO was produced and then produced more erythrocytes or red blood cells.

00:33 You should also be able to predict the mechanism of hypoxemia.

00:37 And you should go through a couple of clinical scenarios that go through this process.

00:43 Remember the main mechanisms of hypoxemia or hypoventilation or a low PIO2.

00:51 We have a diffusional impairment.

00:54 We have a right to left shunt and a ventilation to perfusion mismatch or inequality.

01:01 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.

01:11 If you have a hypocapnea, you would automatically know that alveolar ventilation rate was high.
