- Concordance for Changes in ORi Values as Compared to Corresponding Changes in PaO2 Values.
研究概览
简要总结
The Oxygen Reserve Index (ORi) is a reference that could help clinicians with their assessments of normoxic and hyperoxic states by scaling the measured absorption information between 0.00 and 1.00. An ORi of 0.00 corresponds to PaO2 values of 100mmHg and below and an ORi of 1.00 corresponds to PaO2 values of 200mmHg and above. This is a prospective, non-blinded, non-randomized study of the Oxygen Reserve Index (ORi) in a clinical setting. It is designed to evaluate the correlations with ORi and changes in PaO2 and the potential use of ORi as an early warning of impending arterial oxygen desaturation.

结局指标
主要结局
Concordance for Changes in ORi Values as Compared to Corresponding Changes in PaO2 Values.
时间窗: Less than 30 minutes
ORi is an index value without a unit and ORi does not directly measure PaO2. Therefore concordance is calculated to evaluate changes in ORi relative to the changes in PaO2.
Sensitivity for Changes in ORi Values as Compared to Corresponding Changes in PaO2 Values.
时间窗: Less than 30 mins
ORi is an index value without a unit and ORi does not directly measure PaO2. Therefore, sensitivity is calculated to evaluate changes in ORi relative to the changes in PaO2.
Specificity for Changes in ORi Values as Compared to Corresponding Changes in PaO2 Values.
时间窗: Less than 30 mins
ORi is an index value without a unit and ORi does not directly measure PaO2. Therefore specificity is calculated to evaluate changes in ORi relative to the changes in PaO2.
