Consistent and Reliable Pulse Oximetry: It really is more than just 
applying a probe



Nikolaus Gravenstein, MD

Professor of Anesthesiology

University of Florida

Gainesville, FL




This clinical discussion of pulse oximetry will cover the background, basics and nuances of pulse oximetry monitoring in critical and acute care hospital settings with the goal of helping caregivers build a mental model of the technology and physiology used in pulse oximetry. The webinar will also focus on common clinical conditions that lead to diminished blood flow to the digits and slower detection of saturation changes, including patient shock, peripheral vascular disease, advanced age, etc. Tips on how to troubleshoot and/or optimize pulse oximeter performance will be shared and pulse oximetry probe site options beyond the finger will be discussed. 


Learning Objectives:

After the completion of this activity, the learner will be able to:

  1. Discuss the evidence to help optimize the when, where, why and how of pulse oximeter use  

  2. Describe the clinical situations that can lead to unreliable pulse oximetry measurements

  3. Discuss the use of Nasal Alar SPO2 probe for the monitoring of select patients
