How STOP-Bang Scores Relate to Oxygen Levels and Airway Difficulty During Breathing Tests

In the high-risk group for Obstructive Sleep Apnea, the highest Oxygen Reserve Index (ORi) value reached during preoxygenation was lower, and the time to reach this value was longer.

• Preoperative peripheral oxygen saturation values were lower in the high-risk group compared to the low-risk group.
• The highest ORi value achieved during preoxygenation was significantly reduced in patients at high risk for OSA.
• ORi values at the end of mask ventilation and at the end of intubation were also lower in the high-risk group.
• The time taken to reach the highest ORi value was significantly prolonged for high-risk patients.
• These findings suggest that monitoring ORi may help assess oxygenation and manage airway difficulties in OSA patients.
