Count to 10 - Anaesthetic Primary Podcast

In today’s episode I cover the ‘Past Saqs’ from ‘Applied Cardiac Physiology.” The first SAQ looks at the consequence of tourniquet release after two hours (01:23) followed by the process’s that cause oliguria in hypovolemic shock (09:45). Then I go through the model answers for CVS responses in severe blood loss (14:39), the effects of infusing Hartmann’s solution (16

Today I'm doing a 'Live Practice Viva'. Thanks to Celia for doing this!! I hope you get some technical and non-technical skills from the video. The two topics were: Immune System and Neurophysiology. Topic 1 starts (02:32) with 1 minute thinking time and Topic 2 starts (07:33). We then go through some feedback. Thanks for watching! As always if you have any feedback let me know at

Today I cover the topic ‘Applied Cardiac Physiology.” This is the biggest topic so far in our cardiology series and I had to divide it into 2 parts. Today I look at the LO’s starting first with the CVS effects of pneumoperitoneum (01:19) and the effects that occur with changes in patient position (06:13). Then I discuss the cardiovascular responses to exercise (12:45), Valsal

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

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 Pressu

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 ep

Today I’m back with the first topic for Cardiac Physiology – ‘Electrophysiology.’ This is a huge first topic despite only covering two learning objects. I start by covering the ionic basis of automaticity (01:22) then look at the normal and abnormal process of cardiac excitation (04:02). I briefly then cover the basis of an ECG (12:58), the factors that affect cardiac elec

I'm back for season 3, in this season I'm going to cover cardiac physiology with the aim to finish this topic before the next primary written sitting. I also have a few announcements including a viva boot camp. If you are interested send me a email: [email protected] Thank as always for listening!

Happy New Year listeners! Today’s "MiniPod" is sadly my last for a few months as I take a break to sit my part 2 exam. I have put a lot in this pod and it’s not really that “mini.” I first start by discussing the foetal circulation and the shunts that help this circulation with the transition from foetal to neonatal circulation (01:30). Then I look at the differences in th

Today’s "MiniPod" reviewed the physiological changes that occur in pregnancy with a focus on the cardiorespiratory systems. I initially give a brief overview of the factors that cause these changes (00:40) followed by first looking at the cardiovascular system changes (02:40) and then the respiratory system (09:42). With these topics it's key to have a structure, describing preg
