Adjustable expiratory relief in respiratory therapy

A respiratory system for delivering a respiratory therapy to a patient, the system configured to adjust a flow rate of gases delivered to the patient according to patient inspiration and expiration, the system comprising:

• a flow generator configured to generate the flow rate of gases;
• and
• a controller in electrical communication with one or more sensors and configured to:
• determine a cycle of the patient inspiration and expiration based on information received from the one or more sensors;
• and
• adjust the flow rate based in part on the cycle of the patient inspiration and expiration,
• wherein the adjusting is attenuated by comparing a maximum and/or minimum flow rate measured by the one or more sensors with a maximum and/or minimum threshold.

A respiratory system for delivering a respiratory therapy to a patient, the system configured to adjust a flow rate of gases delivered to the patient according to patient inspiration and expiration, the system comprising:

• a flow generator with a motor for generating a gases flow;
• and
• a controller in electrical communication with one or more sensors and configured to:
• cause to be displayed, on a user interface of the respiratory system, an expiratory relief level setting;
• receive a first user input to increase and/or decrease an expiratory relief level;
• cause to be displayed, on the user interface, a maximum and/or minimum flow rate threshold setting;
• receive a second user input to increase and/or decrease the maximum and/or minimum flow rate threshold;
• and
• adjust the flow rate based on the first user input and the second user input,
• wherein the first user input is configured to allow adjusting of the flow rate based in part on a cycle of the patient inspiration and expiration and the second user input is configured to attenuate the adjusting based on the first user input by comparing a maximum and/or minimum flow rate measured by the one or more sensors with the maximum and/or minimum threshold.

• a flow generator with a motor for generating a gases flow;
• and
• a controller in electrical communication with one or more sensors and configured to:
• cause to be displayed, on a user interface of the respiratory system, an expiratory relief level setting, the setting comprising a plurality of different expiratory relief levels;
• receive a user input via the user interface to increase and/or decrease an expiratory relief level;
• and
• adjust the flow rate based on the user input, wherein the user input is configured to allow adjusting of the flow rate based in part on a cycle of the patient inspiration and expiration.
