Tidal Volume by Predicted Body Weight
Calculate lung-protective tidal volume target for ventilated patients.
- Formula
- TV = 6 mL/kg x IBW, range often 6-8 mL/kg IBW.
- Clinical context
- Lung-protective ventilation with TV 6 mL/kg IBW reduces mortality in ARDS.
- Limitations
- Maintain plateau pressure < 30 cm H2O and driving pressure targets per local guidance.
