Today I cover the topic ‘Regional Circulation.” This has one very big learning objective that looks at the factors that govern blood pressure. To understand this, we have to first understand how the systemic circulation works (02:29) and second the physics which control blood flow (08:42), together this helps us to understand the factors that make blood pressure (18:07). I then take a deeper look at total peripheral vascular resistance (19:55) and microcirculation (24:49). The BIG topic for today is understanding the control arc of blood pressure (32:04) and this includes talking about the baroreceptor reflex. Finally, we look at some past SAQs (42:06). Next episode I will go through ‘Applied Cardiac Physiology.’ Thanks for listening! As always if you have any feedback let me know

Today I cover a huge topic ‘Control of Cardiac Output & Pressure.” This used to be one big learning objective with 4 subsections that I will go through today. Frist I define and describe the classic terms of preload, afterload and contractility (01:19). Then I delve into the frank starling mechanism (12:34). Followed by a long look at the Guyton Curves (16:02) and the LV Pressure-Volume Loop (28:38). At the end I have some time to look at the past SAQs (34:04). This is a very diagram heavy topic and I highly recommend reviewing these diagrams in detail in preparation for the exam. Next episode I will go through ‘Regional Circulation.’ Thanks for listening!

Today I cover the ‘Myocardial Oxygen Supply and Demand.' This topic has 2 main learning objectives, first I cover the anatomy of the heart including the coronary vessels (0:55) and then take a more in depth look at the factors that affect supply and demand (12:54). As always, I end with reviewing the past SAQs, today I have some from the ANZCA and the CICM exams (27:10). Next episode I will go through ‘Control of Cardia Output and Pressure.’ Thanks for listening! As always if you have any feedback let me know
