Less than expected values occur<br>in obstructive and restrictive pulmonary diseases.<br>\u25aa Forced expiratory volume in 1 second (FEV1): Volume of air expelled<br>during the first second of FVC. In obstructive pulmonary disease, airways<br>are narrowed and resistance to flow is high. Therefore not so much air can<br>be expelled in 1 second, and FEV1 is less than the predicted value. In<br>restrictive lung disease, FEV1 is decreased because the amount of air<br>originally inhaled is low, not because of airway resistance. Therefore the<br>FEV1\/FVC ratio should be measured. In restrictive lung disease a normal<br>value is 80%, and in obstructive lung disease this ratio is considerably<br>less. The FEV1 value will reliably improve with bronchodilator therapy if<br>a spastic component to obstructive pulmonary disease exists. .<br>o Spirometry: Greater than 80% of expected value is normal<br>o Airflow rate: Diminished at less than 60% of normal.

Some risk factors for COPD include<br>smoking, pollution exposure, and genetic predisposition.
