Context Menu
Pressing and holding the Vt parameter button brings up the Vt context menu that includes:
•
Compliance
•
Adult
•
Infant
•
Compliance Volume
The tubing compliance can be set to off, adult, or infant.
Users can chose to use the adult or infant circuit defaults for the standard ZOLL adult/pediatric
and infant/pediatric patient circuits.
The patient circuit is part of the breathing system of the ventilator. Tubing compliance of the
circuit is a physical property that affects the tidal volume delivered to the patient. The ventilator
allows you to adjust the compliance value of the circuit (see Chapter 6 for more information).
Tubing compliance is adjustable and a different compliance value can be entered for each
circuit type by selecting either of the menu items. The range is limited for the adult patient
circuits from 0 to 3.5 ml/ cm H
2
O and from 0 to 2 ml/ cm H
2
O for the infant circuits to prevent
a selection beyond the range of the standard circuits.
In order to prevent inappropriate or unsafe use of this feature, the tubing compliance
compensation is turned OFF at startup.
Adult and Infant settings correspond to the standard WYE patient circuit used. Adult CT range
is between 0 and 3.50 ml/cm H
2
O (default of 1.60 ml/cm H
2
O), and the Infant CT range is
between 0 and 2.00 ml/cm H
2
O (default of.5 ml/cm H
2
O).
During volume targeted breathes the ventilator corrects for the loss due to CT by adding the
correction to the set Vt ensuring that the set volume is delivered to the patient. During pressure
targeted breaths the compensation volume is subtracted from the displayed Vt to indicate the
volume delivered to the patient.
