Abstract
A method of controlling a flow rate of gases supplied to a patient by a respiratory assistance device includes controlling the supply gases flow rate so as to deliver gases to the patient according to a predetermined gases pressure/flow rate profile for at least a portion of the breathing cycle. A profile may be achieved that provides the patient with a particular benefit or therapy.

A method of controlling a flow rate of respiratory gases supplied to a patient, the method comprising:
- controlling the flow rate of respiratory gases supplied to the patient according to a predetermined gases pressure/flow rate profile in a mode defined for at least a portion of a breathing cycle of the patient,
- wherein the predetermined gases pressure/flow rate profile is configured to control the flow rate of respiratory gases supplied to the patient such that respiratory gases are supplied at a substantially constant pressure for a predetermined portion of the breathing cycle.
A respiratory assistance device comprising:
- a controller configured to control a flow rate of respiratory gases supplied to a patient according to a predetermined gases pressure/flow rate profile in a mode defined for at least a portion of a breathing cycle of the patient,
- a controller further configured to control the flow rate of respiratory gases such that the predetermined gases pressure/flow rate profile is configured to control the flow rate of respiratory gases supplied to the patient such that respiratory gases are supplied at a substantially constant pressure for a predetermined portion of the breathing cycle.
