Brief Summary

Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) denotes the use of high-flow humidified nasal oxygen system (for example Optiflow®) as an alternative ventilation modality for an anesthetized patient without spontaneous respiration. This method requires only basic airway management manoeuvres to keep the airway open and provides both stable longterm oxygenation as well as apneic ventialtion. We plan to evaluate this methods physiological performance under standardized conditions of airway management by frequent, repeated arterial blood gas analyses.
