A patient with severe COPD has a very difficult time managing everyday tasks such as stair climbing. • (Spirometry test) The patient is asked to inhale and then forcefully exhale until the lungs are completely emptied via a tube attached to a recording device. • The most important values from the spirometry readings are FEV1 and FVC. • If the ratio of these values is less than 0.7 then COPD is suspected. More detailed results from spirometry can reveal the stage of COPD in the patient.
