Oxygenation by 100% Oxygen Via High Flow Nasal Cannula in Surgical Patients

Evaluation of Oxygenation by 100% Oxygen Via High Flow Nasal Cannula During Apnea in Adult Elective Surgical ENT Patients

Oxygenation with high-flow nasal cannula with 100% oxygen has only been evaluated in a limited number of studies. Although data are convincing it is of importance to evaluate this new concept in our department before implementing it into clinical practice.

The general purpose of this project is to evaluate a new ventilation strategy during ENT-surgery based on oxygenation with high-flow nasal cannula with 100% oxygen with focus on gas exchange.

Inclusion Criteria:

1. Adult, >18 years old
2. ENT-surgery where apnea is of benefit for the surgeon (eg. intraoral or laryngeal surgery) and the anesthesia time is <40 mins.
3. Capable of understanding the study information and sign the written consent.

Exclusion Criteria:

1. ASA>2
2. NYHA >2
3. BMI >30
4. Pregnancy
5. Manifest cardiac failure or coronary disease
6. Neuromuscular disease
