    摘要： A humidifier for a respiratory apparatus for delivering a humidified flow of breathable gas to a patient includes a humidifier chamber configured to store a supply of water to humidify the flow of breathable gas, the humidifier chamber comprising a first heating element configured to heat the supply of water; a relative humidity sensor to detect a relative humidity of ambient air and generate signals indicative of the ambient relative humidity; a first temperature sensor to detect a temperature of ambient air and generate signals indicative of the ambient temperature; and a controller configured to determine an absolute humidity of the ambient air from the signals generated by the relative humidity sensor and the first temperature sensor and to control the first heating element to provide a predetermined relative humidity to the flow of breathable gas. A method of humidifying a flow of breathable gas to be provided to a patient includes determining an absolute humidity of ambient air used to form the flow of breathable gas; and controlling a temperature of a supply of water that humidifies the flow of breathable gas to provide a predetermined absolute humidity corresponding to a predetermined temperature and a predetermined relative humidity of the flow to be delivered to the patient.

    摘要： A humidifier (14) for humidifying a flow of breathable gas to be delivered to a patient includes a chamber (16) configured to receive the flow of breathable gas; a tub (20) configured to contain a supply of water, the tub being configured to be inserted into the chamber; a lid (18) provided on the chamber and being movable between an open position and a closed position; and a seal (19) provided on the lid, the seal being configured to seal the chamber such that the flow of breathable gas pressurizes the chamber. The humidifier may be connectable to a flow generator (12) configured to generate the flow of breathable gas. A tube for delivering the humidified flow may be connected to the humidifier. The tube may be a heated or non-heated tube. A respiratory apparatus for delivering a flow of breathable gas to a patient may include the humidifier and the flow generator and/or the tube. A method of humidifying a flow of breathable gas comprises sealing a chamber containing a supplying a water and pressurizing the chamber by directing the flow of breathable gas into the chamber.
