Soldier,
I have asthma and have a 30% rating. My rating was based on the need for daily Advair and Singulair to control symptoms. Still have difficulty breathing, especially in moldy, damp, and cold weather ares. pulmonary Function Studies showed FEV-1 to be 93 percent predicted and fev-1/FVC to be 74 percent predicted. The interpretation shows mild airway obstruction with significant improvement after bronchodilators.....
For and evaluation fo 30%: "for forced expiratory volume in one second (FEV-1) of 56-70 percent of predicted value; or .... (FEV1/FVC) of 56 to 70 %......or daily inhalational or oral bronchodilator therapy: or inhalational anti-inflammatory medications. A higher rating of 60% is not warranted unless there is FEV-1 of 40 to 55 percent predicted; or FEV-1/FVC or 40 to 55 percent: or at least monthly visits to a physician for required care of exacerbations; or intermettent ( at least thre per year) courses of systemc (oral or parenteral) corticosteroids.
Mine is basically because of the daily meds I have to take. In my record is a letter from the Allery doc and the pulmonary clinic on how the "refused" to give me a histamin challange test as I had over a 25% change in FEV-1 with a bronchodialator..... i.e. they might have killed me by inducing an asthma attack. This is strait from my award letter, on the Blue sheets.
Hope it helps.
