Airvo/Optiflow High Flow Nasal Oxygenation During Microlaryngeal Surgery

Stopped: Airvo 2 not suitable for CO2 clearance, awaiting Optiflow THRIVE machine

Singapore0Started 2016-06

Plain-language summary

Optiflow high flow nasal cannula (HFNC) oxygenation is a technique to provide oxygen to patients when they are paralysed under general anaesthesia. Their lungs are not moving, but the high flow allows oxygen to travel into their lungs. This is called 'apnoeic ventilation'. The investigators will be using this for patients undergoing surgery for their throat.
