  1. Oxygen therapy in copdNordic congress in general practice 2009 Jón Steinar Jónsson gp 09

  2. O2 therapy in copd • Increase life expectancy in copd patients with chronic hypoxemi (PaO2<7,4 kPa) • Decrease symtoms of hypoxemi such as edema but has little effect on dyspne • In moderate hypoxemi (PaO2 7,4-8 kPa), same effect on symptoms Jón Steinar Jónsson gp 09

  3. NICENational institute for Health and Clinical excellence: • 1.2.7.2 LTOT is indicated in patients with COPD who have a PaO2 less than 7.3 kPa when stable or a PaO2greater than 7.3 and less than 8 kPa when stable and one of: secondary polycythaemia, nocturnal hypoxaemia (oxygen saturation of arterial blood [SaO2] less than 90% for more than 30% of time), peripheral oedema or pulmonary hypertension. • A Jón Steinar Jónsson gp 09

  4. NICE • 1.2.7.3 To get the benefits of LTOT patients should breathe supplemental oxygen for at least 15 hours per day. Greater benefits are seen in patients receiving oxygen for 20 hours per day. A Jón Steinar Jónsson gp 09

  5. Oxygen therapy in copd • 1.2.7.4 The need for oxygen therapy should be assessed in: ･ • all patients with severe airflow obstruction (FEV1less than 30% predicted) • ･ patients with cyanosis ･ • patients with polycythaemia ･ • patients with peripheral oedema ･ • patients with a raised jugular venous pressure • patients with oxygen saturations less than or equal to 92% breathing air. • Assessment should also be considered in patients with moderate airflow obstruction (FEV130-49% predicted). • D Jón Steinar Jónsson gp 09

  6. Oxygen therapy in copd • 1.2.7.5 To ensure all patients eligible for long-term oxygen therapy (LTOT) are identified, pulse oximetry should be available in all healthcare settings. • D Jón Steinar Jónsson gp 09

  8. Grading scheme • A - systematic reviews or metaanalysis • B - controlled trials • D - expert committee report Jón Steinar Jónsson gp 09
