Abstract

Airway obstruction at Extra thoracic (central) or intra thoracic (peripheral) level  can be satisfactorily diagnosed by recording conventional   spirographic  tracings using simple standard instruments such as Peak Flow meter and  closed spirometer which are easily available in all Hospitals. Ventilatory parameters and certain Ratios derived from them which would permit maximum separation between normal subjects and those with central or peripheral airway obstruction are to be routinely performed in all laboratories for assessment of the site and degree of airway obstruction and treatment. The merits of these different parameters are discussed over here
