Phoenix Sepsis Score (pediatric)
Phoenix Sepsis Score (2024 SCCM/JAMA international consensus) — an organ-dysfunction score across four systems: respiratory (0-3), cardiovascular (0-6), coagulation (0-2), neurologic (0-2), total 0-13.

Example
- Age
- 24 months
- Oxygenation ratio type
- PaO₂/FiO₂
- Oxygenation ratio value
- 150
- Respiratory support
- Invasive mechanical ventilation
- Vasoactive medications
- 1
- Lactate
- 6 mmol/L
- Mean arterial pressure

Result: Phoenix Sepsis Score 8/13
The tool opens with these values already filled in. Replace them with your own.
What the result means
- 0–1
- Below the Phoenix organ-dysfunction threshold for sepsis.
- ≥ 2
- In a child with suspected/confirmed infection, meets the consensus definition of sepsis.
- CV ≥ 1
- Sepsis with a cardiovascular sub-score ≥ 1 meets the consensus definition of septic shock.
