So if needed you can give this bronchodilator drug through nebulization at home. Arterial oxygen level also should be checked for low than oxygen therapy. Also needed to assess severity pulmonary function test. Consult pulmonologist for examination and decide management plan accordingly.Hope I have answered your query.
