Podcast 188 - Sodium Nitrite Ingestion & Methemoglobinemia w/ Dr. Brookeman

In this episode of the FOAMfrat Podcast, Dr. Harrison Brookeman joins the discussion to examine methemoglobinemia and the emerging prehospital threat of sodium nitrite ingestion. Often viewed as a rare toxicology concept, this condition is appearing more frequently and can progress rapidly with devastating consequences if it is not recognized early. The episode focuses on what matters most to EMS clinicians in the field: the physiology of methemoglobinemia, why these patients appear profoundly hypoxic despite adequate ventilation, and the classic clue: a pulse oximetry reading that remains fixed around 85 percent regardless of oxygen delivery. The conversation also addresses iatrogenic causes such as benzocaine exposure, expected mental status changes, and why oxygen alone does not correct the problem. Emphasis is placed on prehospital decision-making, including early involvement with poison control, transport destination considerations, and the importance of ensuring these patients are taken to the right facility the first time. This episode is intended to sharpen recognition, improve pattern awareness, and prepare providers for a call that does not follow typical respiratory failure patterns.

Podcast 187 - Dynamic PEEP? | Ventilation Strategies for Metabolic Acidosis w/ Melody Bishop, RRT

A little over a year ago, I made a short reel discussing ventilating a patient in a severe metabolic acidosis. In the video, I mentioned that minimal to no PEEP might be appropriate. Not because the patient doesn’t need PEEP, but because the shortened cycle time at higher respiratory rates can unintentionally generate dynamic PEEP on its own. But what if it was intentional? What if the presence of a wider pressure when the ventilator switches into exhalation would cause the air to exit more rapidly? In this podcast, I discuss my thought process with respiratory therapist extraordinare, Melody Bishop @melodybishop_rt. She helps surface some definitions and distinctions to terms like air-trapping, Set PEEP, & auto-PEEP while we discuss ventilation strategies in metabolic acidosis. The blog below was what I had sent her before the podcast to get all my thoughts & illustrations down in writing. As always, please follow your local guidelines, and I hope you enjoy listening to the conversation.  

Podcast 186 - Should we throw away our pelvic binders? w/ Dr John Lyng

Pelvic binders have long been considered a standard intervention in the management of suspected pelvic fractures in the prehospital setting. However, recent guidance from the National Association of EMS Physicians (NAEMSP) challenges some of the long-standing assumptions surrounding their use. In a recent FOAMfrat podcast episode, I spoke with Dr. John Lyng, editor-in-chief of the NAEMSP Trauma Compendium, to explore the evidence and rationale behind their newly released position statement on pelvic fracture management.

Podcast 185 - Eating Disorders w Hanna Thompson

In this episode, Tyler sits down with Hanna Thompson to discuss a critical yet often overlooked topic in EMS—eating disorders. Drawing from personal experience and clinical insight, they explore how these conditions present both medically and behaviorally, especially in prehospital and interfacility transport settings. They break down the subtle physical signs that EMS providers can look for—such as Russell's sign, lanugo, unexplained bradycardia, and electrolyte disturbances—and emphasize the importance of sensitive history taking. The conversation also dives into the dangers of refeeding syndrome, slow correction strategies, fluid choice, and the clinical significance of thiamine, magnesium, and phosphate replacement. What You’ll Learn: How eating disorders can manifest in EMS calls Why you may be treating the consequences, not the disorder itself Red flags like bradycardia, lanugo, and Russell’s sign How to handle refeeding syndrome safely Why dextrose, fluids, and electrolyte replacement should be approached cautiously The connection between electrolyte shifts and seizures or arrhythmias Key Takeaway: Patients with eating disorders are medically and psychologically fragile. In EMS, we often encounter them through the effects of the disorder—not the diagnosis itself. Recognizing subtle clues and avoiding aggressive interventions could save a life.

Podcast 184 - Diastolic Augmentation w/ Brian Cress

In this episode, Tyler Christifulli sits down with cardiac perfusionist Brian Cress to dig into the physiology of coronary perfusion, the mechanics of the intra-aortic balloon pump (IABP), and the clinical finesse of diastolic augmentation. Whether you're just starting to encounter balloon pumps or want to sharpen your transport strategy, this discussion is packed with visual metaphors, waveform analysis, and real-world pearls.
