Oxygen Saturation Target Selection
Selects appropriate SpO2 target range based on clinical condition. Prevents both hypoxia and oxygen toxicity (hyperoxia). Based on BTS Oxygen Guidelines.
Score interpretation
→ Start O2 if SpO2 <94%; titrate device: nasal prongs 1-4L/min (SpO2 90-94%), simple mask 5-10L/min, non-rebreathe 15L/min for acute severe hypoxia; wean O2 once target maintained; ABG if uncertain
→ Start O2 via 28% Venturi mask (2L/min); check ABG after 30-60 min; if PaCO2 rising or pH falling: NIV (CPAP or BiPAP); do not withhold O2 if severely hypoxic — aim 88-92% while arranging NIV
→ Use 100% O2 via NRB mask or BVM during resuscitation; switch to titrated O2 post-ROSC (target SpO2 94-98% or 88-92% if COPD); avoid prolonged hyperoxia post-ROSC (increased mortality)
Interpretation bands for the O2 Target SpO2. Apply clinical judgement and local guidance.
