Patent ID: 8474455

Claim:
A circuit compliance compensated volume assured pressure control system, comprising: a circuit compliance estimator, operative to estimate a patient circuit compliance; a patient circuit volume estimator, operative to estimate a circuit volume VOL CKT — EST based on the patient circuit compliance and a patient estimated pressure P y ; a patient volume observer, operative to estimate a patient volume VOL TID — EST based on a measure delivered net volume VOL NET and the patient circuit compliance; a volume assurance controller, operative to generate a circuit compliance volume compensation factor VOL TID — CTL based on a preset assured volume VOL ASS — SET and the estimated patient volume VOL TID — EST , and a decelerating inspiratory flow corrector, operative to generate a decelerating inspiratory flow command based on a preset inspiratory time T INSP , the volume compensation factor VOL TID — CTL and a preset assured volume VOL ASS — SET .
