AIMS: Continuous pulse oximetry monitoring has been used in patient deterioration recognition systems for decades. For patients on supplemental O2, questions related to the effectiveness of this approach have been raised due to elevation of SpO2 from O2 therapy. We examine this issue in the context of a stable inpatient continuous pulse oximetry-based rescue system with the aim of ascertaining if patients receiving supplemental oxygen are at risk of experiencing clinically meaningful delays in deterioration recognition as compared to patients on room air. DESIGN: Retrospective observational analysis. METHODS: Clinical markers of deterioration recognition timeliness and impact were compared for patients receiving various levels of supplemental oxygen and those on room air over 6 years. Chart review was conducted to assess cause and likelihood of preventability and improvement in detection with other monitoring modalities for emergent cases. RESULTS: Analysis adjusted for patient characteristics, and population level supplemental oxygen use showed no difference between patients on supplemental oxygen vs. room air for transfer rate, emergent transfer rate, or death after rescue or transfer. Analysis excluding population supplemental oxygen modeling showed limited increases in event likelihood, but not for emergent transfers. Chart review of emergent transfers revealed no pattern of delay in recognition of deterioration for patients on supplemental oxygen. CONCLUSIONS: This study...
