    摘要： Components for a respiratory treatment apparatus that is capable of providing a humidified respiratory treatment permit a reduction in condensation in a patient interface and/or its gas delivery tubing. In some embodiments, a rainout valve that may be an integrated component of a humidifier output aperture, or coupled thereto, may reduce condensation with a vapor barrier operable to selectively block and permit humidified gas transfer from the humidifier. For example, the barrier may be operable to open in response to a flow of pressurized breathable gas that may be generated by a flow generator of the respiratory treatment apparatus. In the absence of such a generation of pressurized flow, the barrier may prevent a transfer of the humidified gas such as into a conduit for a patient interface by retracting to a closed position. Example vapor barriers may include a resilient membrane, cover, bellows, flap, shutter or other suitable valve.

    摘要： The ventilator of the invention uses a respiratory effort sensor that does not rely on respiratory airflow or pressure for synchronization, such as a device that measures movement of the suprasternal notch in response to respiratory efforts. This makes the ventilator relatively immune to leaks. Furthermore, the mask pressure may be modulated so as to servo-control the respiratory effort signal to be zero. Because effort is servo-controlled to be near zero, it is not necessary for the effort signal to be either linear or calibrated, but merely monotonic on effort. Similarly, it is possible to achieve near 100% assistance without having to know or estimate the resistance and compliance of the patient's respiratory system, as in those systems that provide proportional assist ventilation.
