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.
