Abstract:
1. A method of treating lung disease, comprising: delivering positive pressure support to an airway of a patient during a plurality of respiratory cycles that include inhalation phases and exhalation phases, wherein the positive pressure support includes an inspiratory positive airway pressure (IPAP) level and an expiratory positive airway pressure (EPAP) level, wherein the IPAP level is higher than the EPAP level by a pressure differential, wherein the delivery is timed by detecting onsets of the inhalation phases and the exhalation phases; increasing the pressure differential between the IPAP level and the EPAP level for multiple respiratory cycles; and decreasing the pressure differential between the IPAP level and the EPAP level for multiple respiratory cycles, subsequent to the increasing, wherein the increasing and the decreasing are performed regardless of respiratory activity during the plurality of respiratory cycles.
