Oxygen Reserve Index
Conditions
Interventions
•Change in inspiratory oxygen fraction (FiO2):
•Normoxia: room air (FiO2 0.21) (baseline)
•Hyperoxia: 21% to 100% oxygen (FiO2 0.21 to 1.0)
•Hypoxia: breathing mixtures of N2 in air via a tight f

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Validation of the new Oxygen Reserve Index (ORI) by collecting optical data using the Rainbow SET Pulse CO-Oximeter (Masimo Corp.) and comparing them to whole blood references of arterial and venous blood drawn in healthy volunteers | — |
Secondary
| Measure | Time frame |
|---|---|
| •Determination and quantification of the capability of the new Oxygen Reserve Index (ORI) to serve as an early alarm of changes in patient’s oxygen status •Quantification of the effects of changes in inspired oxygen concentration on -cerebral tissue oxygenation (as obtained by near infrared spectroscopy, NIRS). -peripheral tissue oxygenation (as obtained by NIRS). | — |
