Oxygen Therapy

Step 1

Identify Target Saturation

Pick the patient group to set the SpO₂ range you're aiming for.

If unsure
  • Check previous blood gases and ABG history
  • Review past discharge letters for Type 2 respiratory failure
  • Default to 94–98% while clarifying — never withhold oxygen in critical hypoxia
