摘要：
A respiratory humidification system for providing heated and humidified respiratory gases to a patient comprising a liquid flow controller 110 providing a controlled flow of a liquid and a heating system including a heating surface 114 configured to receive the controlled flow of liquid. The system comprises one or more temperature sensors measuring a surface temperature of the heating surface and one or more liquid sensors 117 configured to detect whether the heating surface is wetted in at least one region. The system comprises one or more hardware processors providing deterministic control of a humidity level of gases passing through the system by instructing the liquid flow controller to adjust the controlled flow of liquid received at the heating system and instructing the heating system to adjust the surface temperature of the heating surface. Adjusting the surface temperature of the heating surface provides control to produce a known evaporative area. A heater plate is also provided comprising a printed circuit board or etched foil over-moulded with a surface comprising micro-channels.
