Treat with antibiotics if 2 of the following are present

  • purulent sputum
  • increased SOB

Send sputum for culture if possible and appropriate. Culture most useful where there has been poor clinical response to an empirical antibiotic previously or where antibiotic options are limited e.g. allergy, drug interaction.
