Tidal Volume Calculator (ARDSnet, IBW-Based)
Lung-protective 4–8 mL/kg ventilation volumes from height and sex — never actual weight.
Lung size scales with height, not body weight — ventilating a 120 kg patient by actual weight delivers double the safe volume, which is precisely the injury the ARDSnet trial showed killed people (6 vs 12 mL/kg cut mortality 31%→40%... corrected: mortality 31% vs 39.8%). Plateau pressure ≤30 cmH₂O is the companion limit. One of critical care's clearest evidence wins.
