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.

(canceled)
A method of adjusting a respiratory assistance device, the method comprising:
- measuring at least one gases pressure;
- determining at least one of a first predetermined gases pressure/flow rate profile and a second predetermined gases pressure/flow rate profile for controlling a flow rate of respiratory gases supplied to a patient;
- and
- adjusting at least one of the first predetermined gases pressure/flow rate profile and the second predetermined gases pressure/flow rate profile in response to the measured at least one gases pressure.
A respiratory assistance device comprising:
- a controller configured to measure at least one gases pressure;
- the controller configured to control a flow rate of respiratory gases according to a first predetermined gases pressure/flow rate profile;
- the controller configured to control a flow rate of respiratory gases according to a second predetermined gases pressure/flow rate profile;
- the controller configured to adjust at least one of the first predetermined gases pressure/flow rate profile and the second predetermined gases pressure/flow rate profile in response to the measure at least one gases pressure;
- and
- wherein the respiratory assistance device is in fluid communication with an inspiratory conduit and a patient interface to deliver gases to a patient.
The respiratory assistance device of claim 16, wherein the at least one gases pressure comprises a positive end expiratory pressure, inspiratory pressure, or expiratory pressure of the patient.
The respiratory assistance device of claim 16, wherein the at least one gases pressure comprises a gases pressure in a gases flow path between the respiratory gases source and a patient airway during inspiration.
The respiratory assistance device of claim 21, wherein the type of conduit and/or patient interface is determined via at least one of a user input, an identification tag associated with the conduit and/or patient interface, and an electrical resistance associated with the equipment.
The respiratory assistance device of claim 21, wherein the data associated with the identification of the type of conduit and/or patient interface includes at least one of the following:
- a patient name, a date, a gas flow rate, and a gas pressure.
