I am an asthma patient since 16, with no power to exercise and bouts of bronchitis. I am using albuterol inhaler without undergoing any tests. I avoided albuterol inhaler after I got admitted in hospital for pneumonia. Instead I am using advair. After a few day had to go to ER for pneumonia. But then a few days ago we had to make an ER trip for another bout of pneumonia. Now I am asked to undergo breathing and asthma test. I really don't know what are they about to do which do bother me. Can any one help me to find what they are going to do for 2 hours?
