Calculate safe tidal volumes based on PBW for ARDS, lung-protective, and standard ventilation strategies. Evidence-based targets per ARDSNet protocol.
Enter values below and click the button to get your result.
For educational reference only. Always verify results with your clinical team and follow your facility's protocols.
Enter the patient's Predicted Body Weight (PBW) in kilograms
Select the ventilation strategy/goal
Click 'Calculate Tidal Volume'
The result shows the target tidal volume range in mL
ARDSNet protocol: 6 mL/kg PBW — reduce to 4 mL/kg if plateau pressure > 30 cmH₂O
Lung-protective ventilation: 6–8 mL/kg PBW for most ICU patients
Standard ventilation: 8–10 mL/kg for non-ARDS, post-operative patients
Monitor plateau pressure — target < 30 cmH₂O in all ARDS patients
Permissive hypercapnia is acceptable to achieve lung-protective volumes
