Brief Summary
High-flow nasal cannula (HFNC) oxygen therapy represents an open circuit ventilation system that uses flows up to 70 L/min of 100% oxygen through the Optiflow THRIVETM device (Fisher and Paykel Healthcare Ltd, Auckland, New Zealand). Compared to conventional oxygen therapy systems, the heating and humidification of the flows facilitate tolerability by the patient, allow to reach higher and more stable inspiratory fractions of oxygen, produce a flow-dependent effect of continuous positive airway pressure and by reducing dead space, have the potential to increase alveolar volume and improve gas exchanges. The use of HFNC is increased in anesthesia as the only airways management technique during short-term procedures under procedural sedation or general anesthesia. Operative hysteroscopy is a short-term procedure (\<30 minutes), usually performed in a day-hospital regimen, under procedural sedation. In case of apnea and/or hypoventilation, or for long and complex hysteroscopic procedures, the patient can be ventilated through facial or laryngeal masks. The primary objective of this prospective randomized controlled trial is to compare the rate of success of ventilation using the THRIVE device to laryngeal mask ventilation during operative hysteroscopies under procedural sedation. Secondary objectives will be the comparison of the percentage of complications in terms of inability to manage the airways, episodes of hypotension, cardiac arrhythmias, post-operative nausea and vomiting, degree of dyspnea and comfort of the patient in the Post-Anesthesia Care Unit between the two methods.

Outcome Measures
Primary Outcomes (1)
Rate of success of ventilation with THRIVE.
Comparison of the rate of success in airways management with the THRIVE system versus positive pressure ventilation by laryngeal mask. The failure of the method will be defined as a CO2 value measured by transcutaneous monitor (Radiometer) \> 65 mmHg AND/OR a peripheral O2 saturation measured by pulse oximeter \< 94%.
Throughout the surgical procedure
Secondary Outcomes (4)
Airway related complications.

Interventions
In the THRIVE group, dedicated Optiflow THRIVE nasal cannulas will be positioned for 100% high flow oxygen therapy at an initial flow of 30 L/min. After induction of anesthesia and throughout the procedure the flow of oxygen will be increased to 70 L/min.
