Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* What is the recruitment rate to the study over 12 months?
* Is the study design acceptable and safe to participants?
Participants will receive high flow nasal oxygen before their breathing tube is removed. The investigators will compare this with standard practice of applying conventional, low-flow oxygen after the breathing tube removed to see if this effects the rate of repeat breathing tube insertion.
The investigators hypothesise that they will recruit 30 participants to the study protocol (15 participants in each group) over 12 months and that our study protocol will be tolerable and acceptable to participants.

SAFEx
Electrical Impedance Tomography recording is commenced 15 minutes prior to planned extubation. High Flow Nasal Therapy (HFNT) is commenced at least 10 minutes prior to planned extubation. At 5 minutes before extubation, the flow rate of HFNT should be established at 60 litres per min (or as high as can be tolerated by the participant) and the fraction of inspired oxygen (FiO2) set at 40 percent. Prior to extubation, endotracheal, infraglottic and supraglottic suctioning are performed. Then, the cuff is let down followed by immediate extubation with simultaneous application of HFNT. 10 minutes after extubation, the FiO2 is weaned in a protocolised manner to 21 percent - or as close to 21 percent as possible over 25 minutes. If the participant is safely weaned onto room air, the flow rate of HFNT is then reduced in a protocolised manner over 120 minutes: 60 minutes at 60 litres per minute (or the highest flow rate tolerated) and then 60 minutes at 30 Litres per minute.

Standard Care
Electrical Impedance Tomography recording commenced 15 minutes prior to planned extubation. Prior to extubation, endotracheal, infraglottic and supraglottic suctioning are performed. Then, the cuff is let down followed by immediate extubation on to low flow conventional oxygen with a fraction of inspired oxygen of up to 40 percent. Then, the participant is weaned at the discretion of their clinician over the next 2 hours and 35 minutes.
Conventional Oxygen Therapy
Low flow oxygen delivery device (Flow rate between 2 litres per minute and 15 litres per minute)
