Oxygen Reserve Index and Arterial Partial Pressure of Oxygen: Relationship in Open Heart Surgery
Authors' conclusion
The preserved relationship between ORI and PaO2 in the mild and moderate hyperoxic range can allow more precise titration of oxygen therapy to guide therapy targeting normoxia, mildly and moderately hyperoxia.
Study context
- Population
- Patients undergoing valve, aortic arch and coronary artery bypass grafting (CABG) surgeries, on and off pump, September 2019–August 2021
- Outcome
- Relationship between ORI and PaO2 in open-heart surgery
Main finding
As reported in the abstract
Correlation of ORI with PaO2 (100-200 mmHg range)
- Oxygen Reserve Index (ORI) vs PaO2 correlation, PaO2 100-200 mmHg (r)
- 0.8193
- P value
- p < 0.001
Observational data: associations, not effects.
Further findings
Correlation of ORI with SpO2 (95%–100% range)
- ORI vs SpO2 correlation, SpO2 95%–100% (r)
- 0.529
- P value
- P < 0.05
