The "Glass Lung" - A Lifelike Electromechanical Lung Simulator
Background: This contribution describes the hardware setup, control, and
parametrization of an electromechanical test lung intended to perform tests with
Methods: We use a nonlinear model to imitate the dynamic behavior of a real
lung in terms of compliance and resistance. Both passive behavior and
spontaneous breathing (weaning) are supported. In automated test sequences,
the test lung mimics a variety of physiological and pathological lung conditions,
Results: We present the results obtained with an approved clinical ventilator in
various modes including pressure-controlled and pressure support ventilation.
Conclusions: All results are clinically consistent with the values expected from
ventilation of a real patient.
