IN-EXSUFFLATION THERAPY AUTO-ADJUSTMENT

摘要

The present disclosure pertains to a method and system configured to in-exsufflate a subject by controlling the in-exsufflation pressure waveform. In some embodiments, the system comprises a pressure generator, a subject interface, one or more sensors, one or more processors, electronic storage, a user interface, and/or other components. The system is configured to assist the subject to loosen and/or expel secretions by inducing a percussive pressure waveform delivered to the subject during inhalation and/or exhalation. The system is configured to control the in-exsufflation therapy delivered to the subject without requiring regular manual setting and/or adjustment of pressures, pressure amplitudes, a frequency range, and/or other parameters of the percussive pressure waveform.

主权项

1. A system configured to in-exsufflate a subject, the system comprising;
(a) a pressure generator configured to generate a flow of breathable gas for delivery to an airway of the subject according to an in-exsufflation therapy regime; (b) a subject interface configured to place the pressure generator in fluid communication with the airway of the subject; (c) one or more sensors configured to generate one or more output signals conveying information related to one or more parameters of the flow of gas; and (d) one or more processors configured to execute computer program modules, the computer program modules comprising:
(1) a control module configured to control the pressure generator according to the in-exsufflation therapy regime, wherein controlling the pressure generator according to the in-exsufflation therapy regime comprises:
(i) causing the pressure generator to modulate a gas pressure within a respiratory phase between two or more pressure levels to generate a percussive pressure waveform for delivery to the airway of the subject during the respiratory phase; and(ii) monitoring the responsiveness of a flow rate of the flow of breathable gas to the modulations in pressure during the respiratory phase;(2) an effectiveness module configured to determine the effectiveness of the in-exsufflation therapy regime, the determination of effectiveness based on the responsiveness of the flow rate to the modulations in pressure; and(3) an adjustment module configured to adjust one or more parameters of the percussive pressure waveform to enhance the responsiveness of the flow rate.
