Abstract:

Systems, methods, and devices for humidifying a breathing gas are presented. The system includes a base unit, a vapor transfer unit, a nasal cannula, and a liquid container. The base unit includes a blower. The vapor transfer unit is external to the base unit and includes a gas passage, a liquid passage, a gas outlet, and a membrane separating the gas passage and the liquid passage. The membrane permits transfer of vapor into the gas passage from liquid in the liquid passage. The nasal cannula is coupled to the gas outlet. The liquid container is configured to reversibly mate with the base unit.
