Lung Disease and Its Affect on the Work of White Blood Cells in the Lungs

At every study visit, participant's will be asked about their medical history and will have a physical exam.

At each study visit, participants will have an intravenous catheter (IV) placed in one of their veins and blood will be drawn from the IV for study testing.

At every study visit, participants will have their lung function assessed. This is done by blowing forcefully at least 3 times into a tube. Testing will be done two times; before and after the use of an Albuterol inhaler.

At every study visit, participating subjects will take 2 puffs of an Albuterol inhaler after the first set of PFTs, but before the second set of PFTs. There will be at least a 30 minute period after the use of the Albuterol inhaler and the second set of PFTs.
