Effect of High-Flow Nasal Oxygen on Laryngoscopic View
Sponsor: Masarykova Nemocnice v Usti nad Labem, Krajska Zdravotni a.s.
Summary
This prospective, multicenter observational study aims to evaluate the effect of different flow rates of high-flow nasal oxygen (HFNO) on the quality of the laryngoscopic view during videolaryngoscopy in adult patients undergoing general anesthesia. Each patient will serve as their own control, with repeated measurements obtained at three different HFNO flow settings (0, 40, and 60 L/min). The study will assess objective and subjective parameters of glottic visualization using standardized scoring systems.

Interventions
HFNO flow 0
Different flows will be applied to patients undergoing general anaesthesia during airway management. In this arm flow will be 0 l/min. During these flows images will be captured using videolaryngoscope.
HFNO flow 40
Different flows will be applied to patients undergoing general anaesthesia during airway management. In this arm flow will 40 l/min. During these flows images will be captured using videolaryngoscope.
HFNO 60
Different flows will be applied to patients undergoing general anaesthesia during airway management. In this arm flow will 60 l/min. During these flows images will be captured using videolaryngoscope.
