OVERVIEW

Curious Clinicians - Pulse Check: Methemoglobin is organized by VCU Health Continuing Education.

Date:
Thursday, March 27, 2025, 12:00 PM - Thursday, December 31, 2026, 11:59 PM

Description:
Why do patients with methemoglobinemia have an oxygen saturation fixed at 85%?

Here’s a case for you: an older patient with lung cancer undergoes an awake intubation with benzocaine. They then experience hypoxemia which stays fixed at 85% despite receiving 100% FiO2 oxygen. The care team does an ABG, which yields chocolate-colored blood with a PO2 of 284. Diagnosis?

Objectives:

Upon completion of this activity, you will be able to:

  1. Review the mechanism why which pulse oximetry works.
  2. Apply the mechanism by which pulse oximetry works to methemoglobinemia.
  3. Generate other stations where pulse oximetry may be unreliable.
