I recently fit tested for a respirator and was told i may suffer from a superimposed obstructive pulmonary impairment? how can i fix this?

Need diagnosis...: Before it can be treated, you first need a definite diagnosis. You will need a pulmonary function test to see if you have obstruction in your airways and if it is reversible with bronchodilators or not. Your family doctor can order the test and then it will be interpreted by a lung doctor. You may need to see a lung doctor, depending on what the test shows. Good luck!
