A dual area pressure pulmonary modulator apparatus which provides constant flow, pressure cycled ventilatory support to patients that is additionally equipped with fluid conduits in the valve mechanism and body that allow the clinician or user to manually actuate inhalation by occluding a fluid path emanating from the modulator. Such feature is useful for when the device stops cycling due to physiological changes of the patient, for determining if the patient is cycling the device or if the device is automatically cycling by nature of its setting, coordinating medical procedures with the breathing of the patient, increasing the PEEP beyond the intrinsic design PEEP of the device for a given PIP setting, increasing inspiratory hold time, and providing an easy to use alternative mode of operation for users with less sophistication.
