NEO-INF Operative modes | iTernIS ADV
10. 3
This operative mode operates similarly to its ADL counterpart. The differences bet-
ween them have to do with the ability to program ventilation parameters in different
ranges. The functional description found in the
ADL/PED Operative Modes
chapter
for the VCV mode applies for this mode in NEO-INF.
The most important points that must be kept in mind in this mode are:
• This mode is intended to deliver a regulated tidal volume. The ventilator works as
a flow controller, where the flow wave is maintained in spite of respiratory impe -
dance variations. The configured volume is obtained by integrating this flow.
• Cycling is based on time, and the flow is calculated and regulated based on the
selected VT and Ti.
• The airway pressure varies and depends on the mechanical characteristics of the
respiratory system.
• If there is a spontaneous requirement from the patient (Inspiratory sensitivity), the
ventilator helps the patient by synchronizing the start of the inspiratory phase with
the respiratory effort.
NOTE
• The ADL/PED Operative Modes chapter has a
more detailed description of the VCV mode and
its typical parameters

The preset values of the tidal volume will depend on the configuration of the
IBW-
based VT
(see the
Start-up and Initial Calibration
chapter). Fig. 10-2 shows the
initial value that result from an
IBW-based VT
default configuration.
