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.

The invention relates to a pneumatic energy harvesting device, comprising a closed circuit of liquid, with an upper chamber (1) from the base of which extend one or more descending tubes (2), which are angled to connect to one or more ascending tubes (3) connected to the upper chamber (1), above the base, a gas injector (4) being arranged in each ascending tube (3), and one or more turbines (6) being arranged in each descending tube (2) or elbow. The upper chamber (1) may comprise a gas suction conduit (5). Ideally, the ascending tube (3) has a cross-section that increases with height.
