Abstract: A dynamic respiratory control device includes a fast-response valve capable of dynamically imposing multiple resistive loads on the flow of respiratory gas to and from a patient. The resistive loads are applied in response to measured flow rates, patient lung volumes, and/or mouthpiece pressures. The device can precisely constrain tidal breathing, provide precise volumetric control of the airway, and impose multiple specific inspiratory and/or expiratory loading functions to evaluate respiratory function. The device is useful for pulmonary function testing, CT and MRI imaging of the chest, combined CT imaging/interventional radiology, radiotherapy delivery to the thorax/abdomen, and/or as a resistive muscle trainer for weaning patients off ventilators and for respiratory muscle training.
