What To Expect: The patient will be asked to take a deep breath and blow into a disposable cardboard tube (looks like a toilet paper tube!) which is attached to the spirometer in order to determine patient's lung size and ability to exchange oxygen for carbon dioxide. This study is often performed prior to a nebulization and then repeated 20 minutes after a nebulization in order to determine if initially there was airway swelling and inflammation.
The patient will need to remove gum and possibly dentures or bridges.
A print out will allow the physician to look at all the measurements and discuss these results with the patient.
