Ten Minute Medic

A newborn is apneic, the heart rate is falling, and your paramedic brain is already reaching for compressions, epinephrine, and every advanced procedure in the bag. Slow down, hero—the problem probably isn’t the heart. In this episode, we unpack why failed lung inflation drives neonatal bradycardia, how functional residual capacity transforms fluid-filled fetal lungs into working gas-exchange organs, and why a rising heart rate is your best evidence that ventilation is effective.

You’ll learn why oxygen alone cannot rescue unopened lungs, how a leaking mask can quietly sabotage the entire resuscitation, and why the most technically impressive intervention is often the wrong one. Before you medicate, intubate, or start pounding on a chest the size of a sandwich, remember: in neonatal resuscitation, ventilation isn’t just part of the treatment—ventilation is the resuscitation.

You learned it in medic school: nitro “opens the coronary arteries,” and giving it to a right ventricular MI can tank your patient. Nice, clean, easy to test—and maybe not nearly as settled as we’ve been pretending.

In this episode of The Ten Minute Medic, we tear into what nitroglycerin actually does to preload and myocardial oxygen demand, why RV infarctions make us nervous, and the surprisingly thin evidence behind one of EMS pharmacology’s most sacred contraindications.

Know the guideline. Follow your protocol. But for crying out loud, don’t stop asking why.

You know the dose: 1 mg every 3–5 minutes. Congratulations—you’ve memorized the box. But do you actually know what epinephrine is doing after you push it? In this episode of The Ten Minute Medic, we dig into why epi doesn’t magically “restart the heart,” how alpha-mediated vasoconstriction and coronary perfusion pressure give the myocardium a fighting chance, why timing differs between shockable and nonshockable arrests, and why getting ROSC isn’t necessarily the same thing as saving a life. We’ll also tackle the uncomfortable evidence behind our favorite little 1-mg syringe. Because if your entire understanding of epinephrine is “the algorithm says give it,” we need to talk.

The clot lands in the lungs—but the right ventricle may be what actually kills the patient. In this episode of the Ten Minute Medic, we follow the deadly chain reaction from rising pulmonary vascular resistance and dead-space ventilation to right-heart failure, obstructive shock, and cardiac arrest. Clear lungs, falling pressure, very bad day—here’s why a pulmonary embolism can make your patient crash frighteningly fast.

ECGs aren’t really about memorizing squiggly lines—they’re about following electricity.

In this episode of The Ten Minute Medic, we trace the heart’s electrical breadcrumbs from the SA node through the atria, AV node, His-Purkinje system, ventricles, and repolarization. You’ll learn why P waves, PR intervals, QRS complexes, and T waves look the way they do—and why a wide QRS should make you ask a physiologic question rather than simply recognize a pattern.

The goal is simple: stop thinking pattern → name and start thinking electricity → physiology → pattern → diagnosis.

Because great ECG interpretation isn’t about having a better memory. It’s about understanding the electrical story the heart is trying to tell you.

Think naloxone's job is to make overdose patients sit up, smile, and tell you what year it is? Think again.

In this episode of Ten Minute Medic, we explain why the real goal isn't creating the world's angriest awake patient—it's restoring breathing. You'll learn how naloxone actually works, why "less is more" is often the smarter strategy, how re-narcotization can sneak up on you, and why experienced paramedics treat respiratory failure—not the level of consciousness.

If you've ever wondered why some patients wake up ready to throw punches instead of saying "thank you," this episode will make perfect sense... and might save you from your own next Naloxone Rodeo.

Because great paramedics don't just reverse overdoses—they understand the physiology behind every dose.

What if every newborn had to completely remodel their cardiovascular system in the first few minutes of life? In this episode of Ten Minute Medic, we make fetal circulation finally make sense. Discover why the foramen ovale and ductus arteriosus are lifesaving shortcuts before birth—but dangerous liabilities afterward.

Using humor, and real-world paramedic applications, you'll learn how a baby's first breath triggers one of the most dramatic physiologic transformations in medicine. If fetal circulation has always felt like a confusing maze, this episode will connect the dots in just ten minutes.

Ever wondered why a patient can go from filling an emesis bag every 30 seconds to complete silence just minutes after you push 4 mg of ondansetron? It isn't because the drug "settles the stomach"—it's because it shuts down a conversation between the gut and the brain.

In this episode of The Ten Minute Medic, you'll finally understand the physiology behind nausea and vomiting, discover why the 5-HT₃ receptor is one of the most important targets in EMS pharmacology, learn why ondansetron works brilliantly for some patients but falls flat for others, and make sense of the QT prolongation warning without the fear or confusion.

If you've ever memorized that ondansetron is an antiemetic but never truly understood why it works, this episode will change the way you think about one of the most frequently administered medications in prehospital care. By the end, you'll stop memorizing drug cards—and start thinking like a clinician.

Today, we're delving into a critical topic that you'll undoubtedly encounter in the field: hemorrhagic shock. By the end of this podcast, you'll have a comprehensive understanding of what hemorrhagic shock is, why it's so dangerous, and why rapid recognition and treatment are crucial. This knowledge will be fundamental to your ability to save lives in emergency situations.

ECG rhythms aren’t random squiggles—they’re the story of an electrical relay race inside the heart. In this episode of Ten Minute Medic, you’ll follow the baton from the SA node to the Purkinje fibers and finally understand why P waves, PR intervals, narrow complexes, wide complexes, and heart blocks look the way they do.

We’ll cover what happens when the runner slows down, drops the baton, takes the scenic route, or starts an entirely separate race—because apparently even cardiac cells can ignore the chain of command. Stop memorizing rhythm strips and start following the electricity.
