Accuracy of Multiple Pulse Oximeters in Stable Critically Ill Patients.

ABSTRACT:

Background

An accurate S_pO2 value is critical in order to optimally titrate oxygen delivery to patients and to follow oxygenation guidelines. Limited prospective data exist on real-world performance of pulse oximeters in critically ill patients. The objective of this study was to assess accuracy and bias of the S_pO2 values measured by several oximeters in hospitalized subjects.

Methods

We included stable adults in the ICU with an arterial catheter in place. Main exclusion criteria were poor S_pO2 signal and S_pO2 > 96%. In each subject, we simultaneously evaluated 4 oximeters: Nonin (Plymouth, Minnesota) embedded in the FreeO₂ device (OxyNov, Québec City, Québec, Canada), Masimo
