Apparatus, system, and method for respiratory biofeedback

A Respiratory Muscle Training (RMT) system comprising:

• a Respiratory Muscle Training (RMT) device;
• and
• a user device comprising a user interface, wherein the user device is configured to:
• receive an indication of initiation of a Respiratory Muscle Strength Test (RMST) using the RMT device;
• provide a visual indication of a target vent aperture setting;
• receive an image of a vent aperture of the RMT device;
• determine if a setting of the vent aperture in the image is within a predetermined range of the target vent aperture setting;
• provide instructions to commence with the RMST in response to the setting of the vent aperture in the image being within the predetermined range of the target vent aperture setting;
• and
• provide instructions to reset the vent aperture of the RMT device in response to the setting of the vent aperture in the image not being within the predetermined range of the target vent aperture setting.

A Respiratory Muscle Training (RMT) device comprising:

• a body defining a chamber;
• a pressure exchange area, wherein the pressure exchange area is separated from the chamber by a diaphragm;
• an electronics section removably attached to the body, wherein a pressure sensor of the electronics section detects a pressure within the pressure exchange area;
• and
• a vent, wherein the vent enables air received into the chamber from a mouthpiece to enter or exit the chamber.
