Electrical Modeling and Analysis of Human Respiratory System
Bulletin of Scientific Research
The human respiratory system mainly consists of four parts namely trachea, main bronchi, bronchioles and alveoli respectively. The alveoli in the lungs are responsible for the transfer of oxygen and carbon-dioxide through capillaries blood vessels leading to the pulmonary vein. A person cannot breathe properly during Chronic Obstructive Pulmonary Disease (COPD) due to abnormal transfer of oxygen and carbon-dioxide. Artificial ventilation is recommended for a person who suffers from COPD with no
... s from COPD with no breathing or abnormal breathing, to manually preserve intact brain function. So, the blood oxygen level required for the person should be continuously monitored using pulse oximeter and controlled automatically using artificial ventilation. Hence, in this paper human respiratory system is modelled as analogies electrical model by using RLC parameters. The analogous electrical model parameters are represented as resistance, inheritance and compliance respectively. Using this analogous electrical model of human respiratory system, time domain and stability analysis are performed to identify COPD condition.
