In this episode of The Nurse Anesthesia Podcast, Jeremy explores the supporting evidence, mechanisms, and clinical applications of high flow nasal oxygenation (HFNO) in anesthesia practice with Simon McDonald and Amanda Virginia. These experts share their insights on how HFNO technology enhances patient safety during airway management, procedural sedation, and extubation.

During their conversation, Jeremy, Simon, and Amanda discuss the development of HFNO, the mechanisms that provide significant physiological benefits for oxygenation, and most importantly…the clinical applications of this therapy in anesthesia practice.

For anesthesia providers who want to take their practice to the next level of advanced oxygenation for patients, this is a must listen!

It's Q&A time with Sass and Jeremy...where they willingly subject themselves—and you—to the intellectual equivalent of laryngoscopy without topicalization! In this episode they dive headfirst (cephalad to caudad of course) into the pharyngeal and laryngeal anatomy that every anesthesia provider thinks they remember… until they don’t. From the classic “wait… is that CN IX or CN X?” moment, to realizing the posterior cricoarytenoid is the only muscle keeping that airway open—this episode rocks the upper airway questions in all the right ways.

But here’s the deal—this isn’t just an academic exercise. There’s a method to the madness.

Question-based learning is one of the most powerful, evidence-based learning strategies out there. Retrieval practice (aka forcing your brain to recall information under pressure) strengthens memory pathways and improves long-term retention far better than passive review.

And let’s be honest… if you’re a CRNA, you’re already living this life thanks to the NBCRNA's MAC program. Quarterly questions aren’t optional—they’re part of the deal. So, let’s get to it and train like we play!

In this episode of The Nurse Anesthesia Podcast, Jeremy talks with Roxane McMurray, DNP, CRNA, APRN who is the creator of the McMurray Enhanced Airway (MEA). The MEA is in a new airway device classification known as “Distal Pharyngeal Airways” or DPAs. Her innovative device is placed orally to help maintain a patent airway in patients who are at risk for upper airway obstruction while under anesthesia or even during airway emergencies.

The MEA facilitates ventilation in several airway management situations and solves many of the problems we encounter with basic airway devices such as oral pharyngeal airways (OPAs) and nasal pharyngeal airways (NPAs), by being better positioned at the junction of the oro- and hypo-pharyngeal space or distal pharyngeal space…thus bypassing the areas that cause upper airway obstruction.

Roxanne has reimagined basic airway management. Her device is being used in critical care areas, EMS, and in anesthesia for monitored anesthesia care cases and difficult airway management situations. If you have not heard of the McMurray Enhanced Airway, and even for those who have…this is a must listen!
