Think a pulse oximeter reading of 100% means your patient is getting enough oxygen? Think again. In this episode of 10 Minute Medic, we'll uncover one of the biggest misconceptions in paramedic education by breaking down the oxygen-hemoglobin dissociation curve in a way that finally makes sense.
Using memorable analogies, real EMS scenarios, and practical field applications, you'll learn why oxygen sometimes refuses to leave hemoglobin, why a "normal" SpO₂ can hide life-threatening illness, and what carbon monoxide, cyanide, hypothermia, and sepsis all have in common.
If you've ever memorized "left shift" and "right shift" without truly understanding them, this episode will change the way you think about oxygen delivery—and make you a better clinician on your very next call.
