To establish diagnosis</p> <p>LUNG FUNCTION TEST</p> <p>2. To evaluate treatment</p> <p>LUNG FUNCTION TEST</p> <p>3. To monitor the nature of disease</p> <p>LUNG FUNCTION TEST</p> <p>4. To determine the degree of disability</p> <p>LUNG FUNCTION TEST</p> <p>5. To determine the prognosis</p> <p>RESIDUAL VOLUMEI. Helium equilibrium ~ Open circuit method</p> <p>~ Close circuit methodII. Body plethysmograph</p> <p>FLOW VOLUME CURVE Maneuver</p> <p> Additional information</p> <p>VENTILATION SCANNINGUsing radioactive gas</p> <p> Xenon Argon</p> <p>DIFFUSION DLCO Single breath method Rebreathing method</p> <p>PERFUSION Dye dilusion</p> <p> Perfusion scanning</p> <p>CONCLUSION Lung function test give information about the disease Spirometry is a simple method to measure ventilation Good preparation and good maneuver is important Serial measurement is necessary</p>
