The SAVE-O2 AI randomized clinical trial evaluated the effectiveness of autonomous oxygen titration in maintaining normoxemia in acutely ill adults receiving supplemental oxygen. Conducted across four US hospitals, the study found that patients using autonomous titration spent a mean of 85% of time in the normoxemia range compared to 63% in the usual care group, with a significant adjusted risk difference of 21 percentage points (P < .001).
Key findings
- The autonomous oxygen titration group spent 85% of time in normoxemia compared to 63% in usual care.
- Time spent in hypoxemia was lower in the autonomous group at 2.0% versus 3.6% in usual care.
- The proportion of time spent in hyperoxemia was significantly reduced in the autonomous group (9.2% vs 29.1%).
Why it matters
This study highlights the potential of autonomous oxygen titration to improve patient outcomes by maintaining appropriate oxygen levels, reducing the risks associated with both hypoxemia and hyperoxemia in acutely ill patients.
