Do clinicians know how to use pulse oximetry? A scoping review.

Area of Science:

• Medical Education
• Clinical Practice
• Health Sciences

Background:

• Vital signs assessment is critical for detecting clinical deterioration.
• Pulse oximetry is a key vital sign for monitoring oxygen saturation.
• Existing research suggests a deficit in clinicians' in-depth understanding of pulse oximetry principles.

Purpose of the Study:

• To scope published evidence on clinicians' knowledge of pulse oximetry.
• To determine the extent of clinicians' understanding of pulse oximeter technology and its correct usage.

Main Methods:

• A scoping review of contemporary research was conducted.
• Studies published in English from 2019 onwards were included.
• Searches were performed in CINAHL, MEDLINE, and PubMed databases, identifying 11 relevant studies.

Main Results:

• Eleven studies met the inclusion criteria for the review.
• Despite widespread use, many clinicians receive minimal education on pulse oximetry.
• A significant portion of clinicians demonstrate a poor understanding of correct pulse oximeter application.

Conclusions:

• Clinicians' knowledge regarding pulse oximetry remains inadequate.
• There is a pressing need for enhanced undergraduate and clinical education on pulse oximetry.
• Healthcare professionals should proactively assess and address gaps in their knowledge of this essential technology.
