1. A ventilation system, comprising:

  • a ventilator operatively having an inspiratory port for supplying an inspiratory gas to a patient and an expiratory port for receiving an expiratory gas from a patient;

    a patient circuit having an inspiratory limb having one end connected to the inspiratory port, an expiratory limb having one end connected to the expiratory port, and a patient piece having one end connected to the other ends of the inspiratory and expiratory limbs and the other end connected to the patient; and

    a circuit compliance compensated pressure regulated volume control system, comprising a pressure-regulated volume controller operative to generate a circuit compliance pressure compensation factor based on a volume error defined as a volume differential between a set tidal volume and a volume actually delivered to the patient.
