A ventilator which accommodates to a patient\s efforts in breathing and to his change in respiratory requirements is provided by a system with a novel control law. The novel control law determines a target ideal pressure-volume wave-form which characterizes the patient\s respiratory requirements; this waveform is constantly modified and corrected during the course of ventilator operation to enable the patient to breathe with minimum ventilation opposition, or fighting.

A ventilator for regulating respiration gas, comprising: a source for transfer of respiration gas in response to a regulatory signal; measuring means coupled to said source for measuring pressure and volume of said respiration gas being transferred by said source and for providing a pressure signal

A ventilator for regulating respiration gas, comprising: a source for transfer of respiration gas in response to a regulatory signal; measuring means coupled to said source for measuring pressure and volume of said respiration gas being transferred by said source and for providing a pressure signal and a volume signal to represent same; and regulator means coupled to said measuring means and said source (a) for generating a pressure target from comparison of said volume signal with a pressure-volume control law, having a predetermined constant term (b) for comparison of said pressure target with said measured pressure signal, and (c) for generation of said regulatory signal to regulate, in response to said comparison of said pressure target, the pressure of said respiration gas in accordance with said pressure-volume control law.
