Apnoeic oxygenation and THRIVE
Primary-viva (basic-science) question on the physiology of apnoeic oxygenation, the THRIVE technique, the comparison with NO-DESAT, the high-risk and difficult-airway applications, and the limitations (patent airway required, rising carbon dioxide, no aspiration protection).

Prompt
Explain the physiology by which apnoeic oxygenation maintains the arterial saturation during apnoea, describe the technique of transnasal humidified rapid-insufflation ventilatory exchange (THRIVE), and outline the clinical situations in which it is most useful and its limitations.
Question
Explain the physiology by which apnoeic oxygenation maintains the arterial saturation during apnoea, describe the technique of transnasal humidified rapid-insufflation ventilatory exchange (THRIVE), and outline the clinical situations in which it is most useful and its limitations[1][3].
