Episode 14: POCUS of the Cricothyroid Membrane

In this episode Jeremy and Mark focus on the cricothyroid membrane. They discuss the anatomy, sizing, vasculature and orientation of this important airway landmark. They then highlight techniques for palpating the cricothyroid membrane, and finish up with a discussion that explains how to use Point of Care Ultrasound (POCUS) to mark where exact position of this membrane is on the neck. This is an episode you won’t want to miss!ReferencesLin J, Bellinger R, Shedd A, et al. Point-of-Care Ultrasound in Airway Evaluation and Management: A Comprehensive Review.
