In this episode of My Favorite Learners, we're breaking down one of the most commonly confused concepts in nurse anesthesia pharmacology: pharmacokinetics vs. pharmacodynamics of inhaled anesthetic agents.
If you've ever confused blood-gas solubility with anesthetic potency, or wondered why hypothermia decreases MAC, this episode is for you!
We'll cover:
💨 Blood-gas solubility and speed of induction
🧠 MAC, anesthetic potency, and CNS effects
📈 FA/FI curves and partial-pressure gradients
🫀 Cardiac output, ventilation, and fresh gas flow
❄️ Hypothermia, CMRO₂, and decreased MAC
💉 Clinical application using a post–cardiac arrest patient
The biggest takeaway?
Pharmacokinetics = How does it get there?
Pharmacodynamics = What does it do once it gets there?
Understanding the difference is essential for anesthesia pharmacology, clinical decision-making, and preparing for the NCE.
Whether you're an SRNA, CRNA student, or anesthesia provider looking for a pharmacology refresher, this episode connects the science to real clinical practice.
