摘要：
A system for humidifying a breathing gas is presented. The system (100) includes a source (124) of pressurized breathing gas (105), an external vapor transfer unit (101), a first gas tube (120) connecting the source of pressurized breathing gas to the gas inlet (104) of the vapor transfer unit and having a first length (L1), a liquid supply having a heater that heats liquid, a first liquid tube coupling the liquid supply to the liquid inlet (110) of the vapor transfer unit, and a second gas tube (128) having a second length (L2) and connecting the gas outlet (106) of the vapor transfer unit to a patient interface (151). The first length is greater than the second length. The vapor transfer unit includes a gas passage (108), a liquid passage (114), and a vapor permeable membrane (116) separating the gas passage and the liquid passage.
