Tidal Volume Estimate (Radford)
Estimate tidal volume using the Radford approximation of 8 mL per kilogram of body weight.
Description
Estimate tidal volume using the Radford approximation of 8 mL per kilogram of body weight.
Tidal Volume Estimate (Radford) is a focused biology tool that estimate tidal volume using the Radford approximation of 8 mL per kilogram of body weight. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use Tidal Volume Estimate (Radford)
Use Tidal Volume Estimate (Radford) when you need to estimate tidal volume using the Radford approximation of 8 mL per kilogram of body weight. Enter Body weight using the definitions and units below so the result can be reproduced.
- Body weight
- A finite measured or assumed value, expressed in kg.
How Tidal Volume Estimate (Radford) calculates the result
The published tool contract uses this rule: Estimate tidal volume using the Radford approximation of 8 mL per kilogram of body weight.1
- Tidal volume
- The calculated tidal volume in mL.
Limitations of Tidal Volume Estimate (Radford)
The output is an estimate tied to the stated model and coefficients; it is not a direct measurement and should retain that label when reported.
Alternative or Complementary measurements
Retain the original Body weight values and their units alongside the result. Total Blood Volume Estimate is useful when you instead need to estimate total blood volume from body weight using the documented reference value of 70 millilitres per kilogram. Bohr Dead Space provides another view by helping you compute physiologic dead space with the Bohr equation: Vd = Vt x (PaCO2 - EtCO2) / PaCO2.
