Development of solar powered smart telehealth system for conditioning monitoring in IMC

This paper introduces an innovative electronic model of the human respiratory system aimed at diagnosing common respiratory disorders such as bronchitis, emphysema, chronic obstructive pulmonary disease (COPD), and pleural effusion. Additionally, it proposes designing hardware capable of automatically controlling oxygen levels. The primary objective is to facilitate the solar powered automatic regulation of patient oxygen flow without the need for constant human supervision. The developed electrical model closely mimics the physiological structure of the human respiratory system, utilizing passive electrical components including resistors (R), inductors (L), and capacitors (C). The input impedance of this model is derived, and various time- domain responses are analyzed to evaluate airway and alveolar conditions. This assessment provides a qualitative evaluation of bronchitis, typically characterized by narrowed bronchi, and emphysema, often associated with air pollution and smoking. This study delves into different disease stages or levels, encompassing average, good, and affected conditions, to offer a comprehensive analysis. To ensure the stability and clinical relevance of the proposed model, a root localization technique is employed for real-time monitoring of the affected respiratory system. Root locus diagrams derived from this technique correspond to expected clinical phenomena in both healthy individuals and COPD patients. As such, this paper presents simulations to demonstrate various respiratory conditions and proposes the development of hardware for controlling oxygen levels.
