- 9. The method of claim 8 wherein the syndrome is selected from the group consisting of paroxysms of dyspnea, cough, wheezing, shortness of breath, hypoxemia, an increase in airway resistance, decreased forced expiratory volumes and flow rates, hyperinflation of the lungs and thorax, increased work of breathing, changes in elastic recoil, abnormal distribution of both ventilation and pulmonary blood flow, mismatched ratios, altered arterial blood gases, and right ventricular hypertrophy.
