The information that we get from this test is very helpful in finding out the cause of breathlessness , difficulty in breathing or persistant cough a person might be experiencing. It is also used as a general check up test as recent studies have shown that this test is helpful in predicting longevity
Breathlessness and breathing difficulty can be caused by a number of conditions including Asthma, COPD (Chronic Obstructive Pulmonary Disease), Nasal or Airway blockage due to various causes, Cardiac failure and psychological factors.
Spirometry helps the physician in
1. Diagnosing the condition like asthma producing breathlessness or cough
2. Estimating the severity of the disease or impairment
3. Estimating the response to bronchodilation ( treatment test).
4. With this information the physician can decide on the best treatment for the individual patient.
5. Estimate the change with time (Trend Analysis) and modify the treatment as required.
6. Estimate the risk of COPD in smokers at the current level of smoking and in persons with family history or other risk factor.
7. Estimate the decrease if smoking is stopped.
8. Estimate the �lung age� at the current level of lung functions before bronchodilation. ( The lung functions normally decline with age and this would be the age of the person with normal lungs)
9. May be a factor in the estimation of longevity as per recent research. Corrective measures may be taken to improve longevity.
