Using presets and working within guidelines
In the Start menu, you can set the patient's height under the “New patient” menu
item. This section explains how the ventilator automatically calculates the ideal tidal
volume using height and gender.
Ideal body weight (IBW) is calculated from stated height (X) as shown below:
Example
IBW (female) = 45 kg + 2.3 kg •
x
2.54 cm
-60
• Child
(1)
(height < 154 cm):
IBW child = 2.05 kg • exp
x
50 cm
IBW (male) = 50 kg + 2.3 kg •
x
2.54 cm
-60
• Adult
(2)
(height > 154 cm):
The tidal volume for the patient is calculated with the aid of ideal body weight and
the setting Vt per body weight (Vt/body weight) in the Operator menu:
• Patient, male, height 185 cm
Vt = IBW •
Vt
body weight
• Setting for Vt/body weight = 6 ml/kg
