Background:

Chronic obstructive pulmonary disease (COPD) significantly impacts ventilatory muscle function.
Previous studies demonstrated the efficacy of target feedback devices for COPD patient training.
A need exists for detailed descriptions of such devices for wider adoption and replication.

Purpose of the Study:

To provide a comprehensive description of the design and functionality of a target feedback device.
To outline the device's utility in conjunction with external resistance for ventilatory muscle training.
To detail the device's adjustable parameters for personalized patient training.

Main Methods:

The target feedback device was constructed using readily available electronic components.
The device integrates with an external resistor to provide training resistance.
Key features include adjustable pressure targets, breathing frequency, inspiratory time, and breathing waveform control.

Main Results:

The target feedback device successfully provides timing and pressure targets during ventilatory muscle training.
Real-time feedback is delivered to patients, indicating target achievement.
The device is relatively simple to construct and allows for adjustable training parameters.

Conclusions:

The described target feedback device is a practical and accessible tool for ventilatory muscle training in COPD patients.
Its customizable features allow for tailored training regimens to improve respiratory function.
This detailed design facilitates the replication and further development of effective pulmonary rehabilitation tools.
