OLD is a progressive disorder which increasingly debilitates the patient. You may have to increase the dose of steroids or try other medicines from the category of `Disease Modifying Anti Asthma Chat Doctor.  Since these medicines are potentially toxic it has to be done under close supervision of a Pulmonologist. You may also discuss the utility of NIPPY (Non-Invasive Positive Pressure Ventilation) with him. Chest physiotherapy and deep breathing exercises by an expert may help to some extent.
