1. A method for controlling respiratory assistance of a subject, the subject having an airway, the method comprising:

  • generating a pressurized flow of breathable gas for delivery to the airway of a subject at an inspiratory pressure level during a breath by the subject, wherein the breath has inspiratory volume during an inspiratory phase and expiratory volume during an expiratory phase;

    determining a breathing rate of the subject;

    adjusting a first volume threshold based on the determined breathing rate;

    monitoring the inspiratory volume of the breath by the subject;

    comparing the inspiratory volume to the first volume threshold to determine when the inspiratory volume of the breath breaches the first volume threshold; and

    responsive to the inspiratory volume of the breath breaching the first volume threshold, temporarily decreasing the pressure of the pressurized flow of breathable gas from the inspiratory pressure level for expiration by the subject.
