Meaning..: This means that air that is inhaled is not fully exhaled. This typically occurs with obstructive lung diseases like asthma, emphysema and chronic bronchitis. If you are not diagnosed with any of these, the next step would be to pursue a pulmonary function test. If you smoke, you need to quit ASAP to avoid worsening. See a lung doctor for diagnosis/treatment. Good luck!
