1. A system comprising:

  • one or more respiratory sensors configured to be coupled with a patient and to generate a respiration waveform representing inspiration and expiration cycles of the patient;

    a processor configured to receive the respiration waveform from the one or more respiratory sensors; and

    a display configured to display a visual element for representing values of an amplitude of the respiration waveform, the visual element comprising;

    a middle portion corresponding to a reference position representative of a transition between the inspiration and the expiration,a first extremity portion extending from the middle portion in a first direction,a second extremity portion extending from the middle portion in a second direction,a value indicator configured to visually depict values of the amplitude of the respiration waveform during the inspiration and the expiration cycles, wherein the amplitude of the respiration waveform comprises an acoustic volume of the patient'"'"'s respiratory sounds, andfirst and second goal indicators positioned between the reference position and the first and second extremity portions, respectively, the first and second goal indicators visually indicating a goal value of the amplitude of the respiration waveform that the patient is to strive to reach during inspiration, wherein the goal value of the amplitude of the respiration waveform comprises a desired acoustic volume of the patient'"'"'s respiratory sounds;

    wherein the processor is configured to;

    illuminate the value indicator responsive to changes in the amplitude of the respiration waveform to expand at least partway toward ends of both the first and second extremity portions during inspiration and to contract at least partway toward the reference position during expiration, andilluminate the first and second goal indicators.
