HIGH-FLOW NASAL OXYGEN DURING ANESTHESIA INDUCTION IN ADULTS WITH CLASS 3 OBESITY: EFFECTS ON SAFE APNEA TIME AND PERI-INTUBATION SAFETY
Introduction: Patients with class 3 obesity have reduced functional residual capacity, increased oxygen consumption, and a shortened safe apnea time during induction of general anesthesia. These physiological features increase the risk of rapid peri-intubation desaturation. High-flow nasal oxygenation (HFNO) may improv...
