Hello, med students. My name is Zach Olson, and today is episode B, breathing.

It is the second episode in our three-part podcast series on the

approach to a crashing patient, or as most people usually think of it, the A, B, C's of

And when you're on your clerkship, I guarantee you these situations are absolutely going to happen

in your calm, controlled, demeanor, and decision making.

A, B, C, A, B, C, A, B, C, are going to make you look like a baller for your attending,

and it's going to get you one huge step closer to dominating your emergency medicine clerkship

and getting that top one-third rank in your slow.

And that is our goal. So, in this episode, there is one thing that I'm going to want you to

understand. This is the big takeaway. When it comes to the A-B-C's, breathing equals two things.
