How to use the predicted body weight and tidal volume calculator
Find predicted body weight from height and sex and the tidal volume at 6 mL per kg for ventilation. Enter height, sex in the fields above; the predicted body weight, tidal volume at 6 ml/kg are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “predicted body weight”, “tidal volume 6 mL/kg”, “ideal body weight ventilator”, “calculate predicted body weight and tidal volume”, “find predicted body weight”.
Formula
Variables
- ht — Height (cm)
- sex — Sex
Worked example
With height = 175 cm, sex = Male, the calculator gives predicted body weight ≈ 70.566 kg; tidal volume at 6 ml/kg ≈ 423.396 mL.
Frequently asked questions
What is the predicted body weight and tidal volume calculator used for?
Find predicted body weight from height and sex and the tidal volume at 6 mL per kg for ventilation. It helps with questions such as “predicted body weight”, “tidal volume 6 mL/kg”, “ideal body weight ventilator”.
What is the formula for the predicted body weight and tidal volume calculation?
Predicted body weight (kg) = sex+0.91 × (ht-152.4). Tidal volume at 6 mL/kg (mL) = 6 × [Predicted body weight]. Here ht is height (cm), sex is sex.
What inputs do I need for the predicted body weight and tidal volume calculator?
You need height in cm, sex. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the predicted body weight and tidal volume calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the predicted body weight and tidal volume result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
