During positive pressure ventilation, a steady supply of air is pumped to the nose during sleep through a tube and mask. The high pressure of the pumped air keeps the upper airways open. Positive pressure ventilation may be used to treat people with sleep apnoea, in which breathing repeatedly ceases for short periods of time during sleep. The treatment needs to be carried out every night during sleep, and it can be given easily at home.
