SYSTEMS AND METHODS FOR CONROLLING HUMIDITY OUTPUT IN A HUMIDIFIER

原文（中国語）

A respiratory assistance system can include a humidifier used for delivery of heated and humidified gases to a patient includes a humidification chamber with an inlet and associated sensor, an associated heater and sensor, an inspiratory conduit with an associated heater and sensor, and an unheated patient interface, such as a face mask. A humidifier can include a control system configured to change a humidification chamber outlet temperature set point or an amount of generated humidity, including for example, a maximum outlet temperature set point, as a function of inlet gas temperature. The control system can reduce and/or minimize rainout (i.e. condensate) while maintaining a substantially consistent humidity in the gases delivered to a patient.
