SMART-COP (CAP severity)
SMART-COP score (Charles 2008) for intensive respiratory or vasopressor support in CAP.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Age
- 55 years
- SBP < 90 mmHg
- No
- Multilobar infiltrates
- No
- Albumin < 3.5 g/dL
- No
- Respiratory rate
- 20 breaths/min
- PaO2
- 90
- SpO2
- 96
- PaO2/FiO2 ratio
- 400
- Heart rate >= 125 bpm
- No
- New-onset confusion
- No
- Arterial pH < 7.35
- No
Result: SMART-COP 0: low risk per Charles 2008.

What the result means
- 0-2
- Low risk per Charles 2008.
- 3-4
- Moderate risk; intensive respiratory or vasopressor support possible per Charles 2008.
- >=5
- High risk of needing intensive respiratory or vasopressor support per Charles 2008.
