SBT readiness + ARDSnet PEEP/FiO2 table
Spontaneous-breathing-trial readiness (Boles 2007) with the ARDSnet PEEP/FiO2 look-up (Brower 2000 / ALVEOLI 2004).
Open the tool → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- PaO2 / FiO2 ratio
- 200
- Current PEEP
- 6 cm H2O
- Current FiO2
- 0.4
- Patient is awake / cooperative
- Yes
- ARDSnet arm
- Low-PEEP arm (Brower 2000)
- Target FiO2 for the ARDSnet PEEP-table lookup
- 0.5
Result: All 5 Boles 2007 readiness criteria met; ARDSnet low-PEEP at FiO2 0.5 -> PEEP 8-10.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- SBT ready
- All five Boles 2007 criteria met; proceed with SBT per institutional protocol.
- SBT not ready
- One or more Boles 2007 criteria failed.
- ARDSnet low-PEEP
- Brower 2000 PEEP/FiO2 table.
- ARDSnet high-PEEP
- ALVEOLI 2004 high-PEEP arm.
What you enter
- PaO2 / FiO2 ratio
- Current PEEP
- Current FiO2 (fraction 0-1)
- Vasopressors at more than minimal dose
- Patient is awake / cooperative
- ARDSnet arm (low = Brower 2000, high = ALVEOLI 2004)
- Target FiO2 for the ARDSnet PEEP-table lookup (optional; not an SBT criterion)
