1. A respiratory treatment apparatus comprising:
- a controllable source of breathable gas;
an inspiratory duct coupled to the controllable source of breathable gas and adapted to carry the breathable gas away from the controllable source to a patient;
a sensor configured to detect a characteristic of the operation of the apparatus;
anda controller coupled with the source of breathable gas, the controller being configured to determine a relation of the characteristic compared to a predetermined threshold, and to operate the source of breathable gas in a plurality of respiratory treatment modes of operation, including a first respirator mode and a second ventilator mode, wherein the controller being further configured to authorize at least one of the plurality of respiratory treatment modes of operation based on the determined relation of the characteristic.

Abstract
A breathing assistance device, capable of operating according to several respiratory modes forming a list of possible modes. The device is equipped with a mechanism for selecting a desired mode from a group of modes that can be selected. The device also includes a mechanism for realizing a configuration diagnostic of the device, a mechanism for associating with authorization level with each possible mode, according to the results of the diagnostic, with the lowest authorization level corresponding to unauthorized modes, a mechanism for authorizing only the selection of authorized modes, in such a way that selecting unauthorized modes is impossible.
