16.7 Calculating tidal volume on the basis
of height
In the start menu, you can set the patient's height under the New
patient menu item.
This section explains how tidal volume is calculated from this.
Ideal body weight (IBW) is calculated from stated height (X) as
shown below:
Child
(1)
(height ≤ 154 cm):
•Adult
(2)
(height > 154 cm):
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) (see “9.4 Patient presets”, page 109):
Example
• Patient, male, height 185 cm
• Setting for Vt/kg BW = 6 ml/kg
