Systems and methods for high velocity nasal insufflation

A system for delivering breathing gas to a patient, the system comprising:

• a base unit comprising a blower;
• a vapor transfer unit external to the base unit and comprising:
• a gas passage,
• a liquid passage,
• a gas outlet, and
• a membrane separating the gas passage and the liquid passage, wherein the membrane permits transfer of vapor into the gas passage from liquid in the liquid passage;
• a nasal cannula coupled to the gas outlet;
• a connector in fluid communication with the blower and the vapor transfer unit, the connector comprising a breathing gas inlet disposed downstream of the blower, a breathing gas outlet disposed upstream of the vapor transfer unit, and an auxiliary port disposed downstream of the breathing gas inlet and upstream of the breathing gas outlet and configured to receive a nebulized medicament, the connector configured to deliver the medicament and the breathing gas to the patient simultaneously;
• and
• a liquid container configured to reversibly mate with the base unit.
