In this short pulm focused podcast, I discuss a host of common exam scenarios that deal with factors that affect blood O2 content. There are no attached slides.
Pulm is classically a hard subject for people to master. In general, there is little variation between what the NBME tests across the USMLEs on pulm topics. In this episode, I try really hard to help you understand and have a solid basis in pulm with a physiological bent on things. I discuss pulmonary physiology but then delve into HY NBME exam scenarios that show up frequently. On Step 2CK, many pulm concepts end up being analysis questions that demand a salient understanding of the underlying physiology. If pulm is an issue, this is the podcast for you. There ARE ATTACHED SLIDES below for some of the flow-volume loops.
In this podcast, I discuss essentially all you need to know about vents as relevant to the USMLE exams (Step 1-3). I also discuss a host of HY ABG scenarios that commonly show up on these exams. There are no slides as all needed information is in the podcast. A more detailed vent podcast will come in a future episode. QUICK CORRECTION- AROUND MINUTE 11, I MISTAKENLY SWITCH WORDS WHEN DEFINING A SHUNT. THE TRUE DEFINITION IS THAT A SHUNT REPRESENTS A REGION OF LUNG THAT IS PERFUSED WITHOUT VENTILATION. MY EXPLANATION IS CORRECT BUT THAT ONE DEFINITION IS WRONG SO TAKE NOTE!
