  1. Increased Effective Lung Volume Following Lung Volume Reduction Surgery in EmphysemaPresented by Leslie Wattkis 02/25/02Homan, Sean MSc; Porter, Samu2el MBBS; Peacock, Morris MBBS; Saccoia, Nunzia A CertSc; Southcott, Anne Marie MBBS; Ruffin, Richard MD, FCCPVolume 120(4) October 2001 pp 1157-1162

  2. Emphysema • Hyperinflation • Dyspena • Decrease motility

  3. Pulmonary function test • Residual volume (RV) • Fractional residual capacity (FRC) • Vital capacity (VC) • Force vital capacity (FVC) • Force expiratory volume (FEV1) • Alveolar volume (VA) • Total lung capacity (TLC)

  4. Lung volume reduction surgery (LVRS) • Elastic recoil of the alveoli ( PEL) • Diffusing capacity of the lung for carbon monoxide (DLCO) • Lung diffusion capacity corrected for alveolar ventilation (KCO)

  5. Post LVRS • Perfusion • ventilation • Partial arterial oxygen PaO2 • Carbon dioxide CaO2 • Increase VA • Increase FEV1 • Increase FVC

  6. Emphysema patients that meet the requirements for surgery show significant improvements once the affected area is removed from the rest of lung tissue

  7. Any question?
