16.7 Calculating tidal volume on the basis
of height
In the start menu, you can set the patient's height under the New

This section explains how tidal volume is calculated from this.
Ideal body weight (IBW) is calculated from stated height (X) as
shown below:
(1)
Child (height
• Adult
The tidal volume for the patient is calculated in the operator menu
with the aid of ideal body weight and the setting Vt per kg body
weight (Vt/kgBW)
Example
• Patient, male, height 185 cm
• Setting for Vt/kg BW = 6 ml/kg
IBW (male) = 50 kg + 2.3 kg
