Abstract
A humidifier in which the temperature of the humidified gases leaving the humidifying chamber of the humidifier is measured. The measured temperature is compared with a predetermined temperature required for a minimum humidity level for humidified gases supplied to a patient and if the measured temperature is less from the predetermined temperature a warning is provided. The humidifier also has a securing device for securing the humidifying chamber to the heater plate of the humidifier. The securing device comprises a sprung gate member which is biased in an upward position to prevent the humidifying chamber from being removed but may be pressed downwardly by a user in order to engage or remove the chamber.
