TLDR
Experimental results on mechanical test lungs show a large improvement in uniform tracking by the adaptive controller over classical PID control methods currently used throughout the ventilator industry.Abstract:
For the control of critical care ventilators, the problem of tracking a desired pressure trajectory within a patient connecting circuit is solved using indirect adaptive control. This control uses an inverse model of patient lung mechanics and the ventilator connecting circuit. Online estimates of physical parameters are provided using standard recursive least squares with forgetting factor. The indirect method achieves robust performance over a wide range of patient conditions, and also since physical estimates of respiratory parameters are available, they can be applied to diagnostics and/or additional control measures for ventilation. This control method has been applied to NPB 840 ventilator hardware in the loop using the real time simulation software, VisSim. Experimental results on mechanical test lungs show a large improvement in uniform tracking by the adaptive controller over classical PID control methods currently used throughout the ventilator industry.read more
