Abstract
A heater system is provided for a respiratory system having a PID feedback control in which the coefficients are adjusted, such as in a warm-up process, to correspond to a likely flow rate of gas through a chamber of heated water based on the difference between heat input and heat output in relation to a temperature set point without the need to directly monitor flow rate or humidity level. A steady-state adjustment of the coefficients based on the behavior of the measured temperature in relation to the set point is also disclosed.
