Principles and limitations of pulse oximetry in patient monitoring
1School of Nursing and Midwifery, University of East Anglia, Norwich.
Abstract:
Although there are many advantages to using pulse oximetry as a tool for monitoring oxygen saturation in arterial blood, there are also potential pitfalls. Nurses must understand its limitations or there is a risk that they may be falsely reassured by inaccurate readings. This article discusses the principles behind pulse oximetry and outlines some common misunderstandings.
