Abstract
Methods and apparatus involve generation of an anti-infection therapy. The method/apparatus may include a controller controlling setting of a respiratory flow therapy device for the therapy. The controller may compute a target flow rate profile for a patient using a margin function, such that the target flow rate profile, according to the margin function, exceeds a minimum inspiratory flow rate profile of the patient's inspiration. The controller may control setting the respiratory flow therapy device to generate a flow of air to a patient interface according to the target flow rate profile, where the generation may be in synchrony with a sensed parameter that is indicative of a breathing cycle of the patient.

A method of a controller controlling setting of a respiratory flow therapy device for an anti-infection therapy, the method comprising:
- computing, by the controller of the respiratory flow therapy device, a target flow rate profile for a patient using a margin function of the patient's breathing, wherein computing the target flow rate profile during inspiration comprises adding the margin function to a minimum inspiratory flow rate profile of the patient's inspiration such that the target flow rate profile exceeds, according to the margin function, the minimum inspiratory flow rate profile, wherein the computing fits a template function, the template function having a shape, to a peak inspiratory flow rate of the patient and an inspiratory time to generate the minimum inspiratory flow rate profile;
- and
- controlling setting of the respiratory flow therapy device to generate a flow of air with the respiratory flow therapy device according to the target flow rate profile, wherein the generation is in synchrony with a sensed parameter that is indicative of a breathing cycle of the patient.
An anti-infection therapy device comprising:
- a pressure generator configured to generate a flow of air at a controllable flow rate to a patient interface;
- and
- a controller configured to:
- compute a target flow rate profile for a patient using a margin function of the patient's breathing, wherein computing the target flow rate profile during inspiration comprises adding the margin function to a minimum inspiratory flow rate profile of the patient's inspiration such that the target flow rate profile exceeds, according to the margin function, the minimum inspiratory flow rate profile, wherein the computing fits a template function, the template function having a shape, to the patient's peak inspiratory flow rate and an inspiratory time to generate the minimum inspiratory flow rate profile;
- and
- control setting of the pressure generator to generate a flow of air to the patient interface according to the target flow rate profile, wherein the generation is in synchrony with a sensed parameter that is indicative of a breathing cycle of the patient.
Anti-infection therapy apparatus comprising:
- means for generating a flow of air at a controllable flow rate to a patient interface;
- means for computing a target flow rate profile for a patient using a margin function of the patient's breathing, wherein computing the target flow rate profile during inspiration comprises adding the margin function to a minimum inspiratory flow rate profile of the patient's inspiration such that the target flow rate profile exceeds, according to the margin function, the minimum inspiratory flow rate profile, wherein the computing fits a template function, the template function having a shape, to the patient's peak inspiratory flow rate and inspiratory time to generate the minimum inspiratory flow rate profile;
- and
- means for controlling the means for generating to generate the flow of air according to the target flow rate profile, wherein the generation is in synchrony with a sensed parameter that is indicative of a breathing cycle of the patient.
