Abstract: A respiratory ventilator device is described herein. The respiratory ventilator device includes an inhaled air assembly, an exhaled air assembly, and a control system operatively coupled to the inhaled air assembly and the exhaled air assembly. The inhaled air assembly is coupled to a patient respiratory circuit and configured to channel a volume of inhalation air to the patient's lungs to assist in patient inhalation. The exhaled air assembly is coupled to the patient respiratory circuit and configured to remove air from the patient's lungs to assist in a patient exhalation. The control system is configured to operate the respiratory ventilator system in an inhalation mode and an exhalation mode.
