Acute Oxygen Therapy

• Acute Oxygen Therapy:

  • For acutely ill patients NOT at risk of hypercapnic respiratory failure – target saturation range is 94 - 98%
  • For acutely ill patients at risk of hypercapnic respiratory failure – target saturation range is 88 - 92%
• Acute Oxygen Therapy:

  • For acutely ill patients at risk of hypercapnic respiratory failure
  • e.g. COPD
  • target saturation range is 88 - 92%
  • 24% Venturi mask → ABG after 30 - 60 mins
  • why do they need an ABG? - to see if we have caused a change in co2 and o2 levels (dont want to cause increase in co2)
  • Repeat ABG after each rise in FiO2
• Acute Oxygen Therapy:

  • Acute hypoxaemia with no risk of hypercapnic respiratory failure
  • e.g. pneumonia or asthma
  • give high FiO2 if required (40 - 60% O2)
  • Use Venturi masks if breathless
