Steady State and Stability Analysis of Respiratory Control System Using Labview

The human respiratory system is a well developed and complex system which is constantly being perturbed by physiologic disturbances. Engineering performed good support in modeling and simulation of the various functional systems of the human body. The modeling of respiratory of the human body is required to understand its operation and pathologies present. This paper describes a steady state model and cheyne stokes breathing model of respiratory control system. Both models are simulated in LabVIEW. The steady state model gives steady state values of O2 and CO2 at sea level and high altitudes which are useful to provide sufficient ventilation to the persons at high altitudes and also used to analyze the stability of normal persons and congestive heart failure persons at high altitudes from cheyne stokes breathing model.
