Sleep apnoea, where a person temporarily stops breathing while they are asleep, can lead to serious health conditions including high blood pressure and increased risk of a stroke, if it is left untreated.

He also has a portable version for when he is travelling, but could other devices also help?
He tests some the latest tech for BBC Click to find out.
