Abstract: This work aims to present a new approach for observing pulmonary hysteresis data, with an emphasis on modifying the Preisach model to represent respiratory hysteresis curves. The representation of pulmonary hysteresis is crucial for a detailed understanding of the respiratory process. Thus, data modeling becomes essential in measuring the pressure and volume curves that generate the respiratory hysteresis curves. Therefore, a study is proposed based on the adaptation of the Preisach model, widely recognized in physics for characterizing the hysteresis of ferromagnetic materials, to represent the phenomenon of pulmonary hysteresis. The idea is to apply this modified model to representative biological signals of volume and pressure, assessing its feasibility in representing the pulmonary hysteresis curves, making it a valid alternative to validate the signal levels captured by measurement equipment. This approach, primarily theoretical, uses simulated signals to demonstrate the suitability of the modified model for representing the characteristics of the curves, with a focus on the teaching process, and with potential for future validation of real data.
