Abstract
A hand-held nebulizer system is provided which nebulizes during the patient's inspiration cycle only. The system includes a universal sensor port adapter which is adapted to fluidly connect an airway device with a sensor port of the system's source of pressurized gas in such a manner as to permit the patient to inhale and exhale atmospheric air, while permitting the use of standard airway devices. A unique valve arrangement is also provided in the device for supplying the pressurized gas which permits the system to be extremely sensitive to small pressure differentials, thereby ensuring that the system detects the respiratory cycle phases of even the weakest patients.
