Today we look at ‘Pulmonary Circulation!’ Lucky for us this is not a big topic and it’s kind of a breather before our next episode. We start by discussion the anatomy of the pulmonary and bronchial circulation (00:52) and outline the differences between the pulmonary and systemic circulation (04:34). The most important LO in this topic is factors that affect pulmonary vascular resistance, and this takes up majority of the episode (09:14). The last LO assesses pulmonary HTN with a brief introduction of drugs used for control/treatment of pulmonary HTN (20:02).  As always, we end by looking at the key SAQs from the ANZCA and ICU exams (23:51) and there is no summary needed today. I will release a Special Episode 2 weeks before the written exam and the next episode we will go through ‘Applied Respiratory Physiology.' Thanks for listening! As always if you have any feedback let me know!
