Health Updated 14 Jun 2026

Tidal Volume Calculator (Lung-Protective Ventilation) is a health and wellness calculator that helps you calculate the volume of a three-dimensional shape or container. The formula used is: IBW = (50 or 45.5) + 2.3 × (height inches − 60); Vt = IBW × mL/kg. Enter values using the units shown next to each input field (e.g. kg, cm, years).

Rates and fees change frequently. Always confirm the current figures with the official authority before relying on this result.
  • For clinical reference only. Always verify against the patient and protocol.

Formula

IBW = (50 or 45.5) + 2.3 × (height inches − 60); Vt = IBW × mL/kg
  • Tidal Volume Calculator (Lung-Protective Ventilation) gives you a fast estimate using your inputs and updates instantly when you change any value.
  • Formula: IBW = (50 or 45.5) + 2.3 × (height inches − 60); Vt = IBW × mL/kg
  • Input definitions: • Height: the numeric height used in the calculation • Target Volume: the numeric target volume used in the calculation
  • Manual method: write down each input, apply the formula step by step, then compare your manual result with the calculator output.
  • Enter values using the units shown next to each input field (e.g. kg, cm, years).
  • This calculator uses widely accepted health formulas and returns screening estimates only. It does not replace a diagnosis from a qualified healthcare professional.
  • Compare your result with published reference ranges. Values outside the normal range warrant a conversation with your doctor.
  • Practical tip: test a low, medium, and high scenario to understand sensitivity before making decisions.

Example Calculation

Inputs
  • Height: 170 cm
  • Target Volume: 7 mL/kg

Suppose you enter: Height = 170, Target Volume = 7. The calculator applies the formula (IBW = (50 or 45.5) + 2.3 × (height inches − 60); Vt = IBW × mL/kg) and shows all output values below. Change any input field to immediately see how the result changes.
