Count to 10 - Anaesthetic Primary Podcast

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 [email protected]

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), Valsalva (16:58) and positive pressure ventilation (22:30). Then we go into depth examining the changes that occur with ageing (28:42) and obesity (32:35). The final LO for today is multiple LO’s in one and a very deep dive looking into all aspects of shock (37:13). In Part 2 of this topic, I will go through the SAQs.  Thanks for listening! As always if you have any feedback let me know

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! As always if you have any feedback let me know

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

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 electrical activity along with the pathway of electrical activity generation in the heart (17:55). Finally, to finish this first mammoth learning objective I describe the mechanical events of the cardiac cycle (21:51). The second learning objective for today cover the process of excitation contraction coupling (28:42) which is favourite of some examiners by linking it to cardiac pharmacology. As always, I end with reviewing the past SAQs, today I have some from the ANZCA and the CICM exams (36:33). Next episode I will go through ‘Myocardial O2 Supply and Demand.’  Thanks for listening!

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 the anatomy of neonatal airway and the clinical implications of this (09:48). Finally, we look that physiological difference between a neonate and adult (15:44). As always we look at the past SAQS (23:48) and opening viva stem (38:38). Hope you guys enjoy the pod and thank you for your support, see you in a few months! If you have any questions please email me! As always thank you for listening!

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 pregnancy by trimesters and having broad subheadings allow you to get breadth of knowledge across. I utilise this approach as we look at the past SAQs (15:18) and then the past opening viva stems (23:45). I hope you enjoy the Podcast and next time we complete our maternal minipod section by talking about the foetal circulation and comparing and contrasting the neonatal and adult respiratory system. If you have any questions please email me! As always thank you for listening!

Today I'm back with another practice Viva. Thanks to Abe for doing this!! I hope you get some technical and non-technical skills from the video. The two topics were: General Anaesthesia/Sleep and Blood glucose/Insulin. Topic 1 starts (01:55) with 1 minute thinking time and Topic 2 starts (07:50). We then go through some feedback.
