Evaluating the Accuracy of Off-Label Placement of Pulse Oximetry Sensors in Comparison to On-Label Placement in the Adult Cardiac Intensive Care Unit Patient Population.

Background: Continuous pulse oximetry (Spo2) is a commonly utilized tool to obtain an indirect, noninvasive measurement of hemoglobin oxygen saturation. Difficulty obtaining measurement with Spo2 sensors can lead nurses to try off-label sites until they find placement that provides a signal. Currently, there is limited evidence to support this application.

Improving Patient Safety by Increasing Staff Knowledge of Evidence-Based Pulse Oximetry Practices.

Background: Pulse oximetry is commonly used in critical care settings to monitor oxygenation status and assist with decision-making regarding oxygen therapy. Although it is imperative that nurses follow manufacturer guidelines, off-label use is common and could affect patient safety.

Objective: To increase staff members' knowledge and reduce the frequency of off-label pulse oximeter placement in the critical care setting.
