Oxygen performance of patients receiving HFNC during colonoscopy.
| Baseline SpO2 before sedation (under room air) | Minimum Spo2 during procedure | aNumber of desaturation | Oxygen flow rate (L/min) and FiO2 | |
|---|---|---|---|---|
| Patient 1 First time procedure | 98-100% | 88% | 1 | Rate:50 FiO2:40% |
| Patient 1 Second time procedure | 96% | 90% | 1 | Rate:50 FiO2:45% |
| Patient 2 | 100% | 98% | 0 | Rate:50 FiO2:40–45% |
| Patient 3 | 95% | 91% | 0 | Rate:50 FiO2:40–45% |
SpO2: peripheral capillary oxygen saturation; FiO2: fraction of inspired oxygen.

Number of desaturation: Spo2<90% for 5 minutes or SpO2 drop more than 5% from baseline for 5 minutes.
