Control circuit for a servo targeting scheme (eg, Proportional Assist Ventilation). Control circuit for a servo targeting scheme (eg, Proportional Assist Ventilation). The controller is designed so that inspiratory pressure as a function of time (P(t)) is proportional to both volume as a function of time (V(t)) and flow as a function of time (V̇(t)). The constant of proportionality K1 represents the amount of elastance to be supported. The constant of proportionality K2 represents the amount of resistance to be supported.
