Clinical takeaway

IBW is used for tidal-volume (mL/kg) and some drugs.

When to use

Weight-based dosing and tidal-volume calculations.

How it works

Devine IBW = (50 male / 45.5 female) + 2.3 × (height in inches − 60). Adjusted BW = IBW + 0.4 × (actual − IBW).

Key points

  • IBW is used for tidal-volume (mL/kg) and some drugs.
  • Adjusted BW is common for dosing in obesity.
  • Always follow the specific drug's weight basis.
