Spirometry 3. Measurement of lung volumes-Plethismography 4. Gas transfer factor 5. Exercise test- walk test, ergometer test 6. ABG Slide 3: Peak flow meter 2. Spirometry 3. Measurement of lung volumes-Plethismography 4. Gas transfer factor 5. Exercise test- walk test, ergometer test 6. ABG Slide 4: Peak Flow Meter Cheapest and easy 2. In absence of spirometer, establish, assess and monitor Bronchial asthma 3. Home management of asthma Spirometry : Spirometry Spirometry is a measure of airflow and lung volumes during forced expiratory manoeuvre from full inspiration. 3 basic things are measured- ? FVC ? FEV1 ? FEV1/FVC Spirometry procedure : Spirometry procedure ? stand or sit straight ? inhale maximally (breathe in all the way) ? get a good seal around the mouth piece ? blow out as hard (not blowing hard enough-apparent obstructive) and as fast as possible ? continue to exhale until he or she can blow no more, at least 6 secs ( stops blowing too early apparent restrictive) ATS criteria : ATS criteria Acceptibility criteria: ? free from artifacts (cough or glottic closure) ? free from leaks ? Good starts, time to PEF <120 millisecs ? acceptable exhalation-at least 6 secs ATS criteria : ATS criteria Reproducibility criteria: ? 3 acceptable manoeuvres ? 2 largest FVC with in .2 l ? 2 largest FEV1 with in .2l Slide 21: Normal Slide 22: uninterpretable Slide 24: Small midrange flow Slide 25: Fixed upper airway obs Slide 26: Variable extrathoracic Slide 28: Mild to mod airway obs Slide 29: Severe obstruction Slide 30: Severe obstruction Slide 31: Restrictive ventilatory defect Slide 33: Methacholine challenge test To establish CVA 2. To exclude eosinophilic bronchitis 3. 20% reduction of FEV1 with <8mg/ml methacholine is considered positive Lung function Tests : Lung function Tests Peak flow meter 2. Spirometry 3. Measurement of lung volumes-Plethismography 4. Gas transfer factor 5. Exercise test- walk test, ergometer test 6. ABG Slide 36: Lung volume measurement ? Essential to establish restrictive lung diseases ? Most important measurements are – TLC, RV, FRC ? In restriction, cardinal feature is low TLC ? In mixed pattern like sarcoidosis, spirometry shows obstruction and lung volumes are reduced Slide 41: Peak flow meter 2. Spirometry 3. Measurement of lung volumes-Plethismography 4. Gas transfer factor 5. Exercise test- walk test, ergometer test 6. ABG Slide 42: Disorders with low DLCO Diseases of pulmonary circulation 2. Diseases of alveoli 3. Cardiac diseases 4. Misc- anaemia,pregnancy,smoking Slide 43: Peak flow meter 2. Spirometry 3. Measurement of lung volumes-Plethismography 4. Gas transfer factor 5. Exercise test- walk test, ergometer test 6. ABG Slide 44: Indications Assess cardiorespiratory functions 2. Sensitive indicator of early alveolar or interstitial diseases 3.
