High-flow nasal oxygen availability for sedation decreases the use of general anesthesia during endoscopic retrograde cholangiopancreatography and endoscopic ultrasound

Figure 3 Use of general anesthesia during eras 1, 2 and 3. During era 2 (HFNO available) significantly less cases were performed under GA compared to era 1, although this difference did not reach statistical significance between eras 2 and 3. HFNO: High-flow nasal oxygen; GA: General anesthesia. ^aP = 0.012 era 1 vs era 2.
