Episode Summary

Nitrous oxide is one the OG of anesthesia gases and is one of three gases pipped into our anesthesia gas machine. It’s known on the anesthesia workstation by the color blue. In this episode Jeremy and Mark discuss the current use of nitrous oxide and both it’sdesirable and undesirable effects. Gear up to review or learn about the “Original Blue Gas”!

This is a special episode where Jeremy & Sass talk with the one and only Dr. John Nagelhout, PhD, CRNA, FAAN. They talk with him about what it was like when he first went to anesthesia school, his transition into academics, how he gathered a group of CRNAs together to write the very first Nurse Anesthesia textbook, and the thousands of lives he’s influenced with his pharmacology lectures.

There’s a reason we call him the “Grand Master of Nurse Anesthesia Education” and this is a piece of history you won’t want to miss!

Episode Summary

The pulse oximeter is a primary anesthesia and critical care monitor. Not only does it help identify hypoxemia, but it provides several other pieces of essential information when monitoring a patient during anesthesia and surgery.

In this episode, we go over how the pulse oximeter functions, the current advantages and disadvantages, and other practical considerations that make pulse oximetry monitoring simple awesome!

Anesthesia induction agents are essential anesthesia medications that anesthesia providers need to learn about and understand so they can select the correct medication for the right patient/situation. The primary induction agents used in today’s anesthesia practice include: Propofol, Etomidate, and Ketamine…we refer to these as “The Knock Out Buch!”

Without a doubt, propofol is used more often than any other anesthesia induction agent.

In today’s episode, we talk about the pharmacokinetics, pharmacodynamics, mechanism of action, and clinical indications of each one of the anesthesia induction medications. Get ready, because this is an episode filled with key concepts and important information used for exams that is hard to find!

In this episode we highlight the various difficult airway algorithms and failed airway checklists developed by professional airway organizations. These tools used by anesthesia providers to develop their personal airway management plans and to help guide decision making in the event of a difficult or failed airway.

We’ve heard from a lot of anesthesia students, RNs, and CRNAs about how they want some question-and-answer episodes…so we’re here to deliver! This is the first Anesthesia Q&A, and we’re calling it Round 1 (ding! ding! ding!). What better way to start Anesthesia Q & A than with some respiratory anatomy and physiology.

We’ve had extensive experience writing questions for anesthesia students, CRNAs, and for national certifying exams. So put the gloves on, it’s time to jump into the ring and dive into some of the favored respiratory topics that are tested in anesthesia school and on national certification exams.
