13. 3
The trends module is a tool used to control the value history of the main ventilating
parameters during the last 72 h of ventilation.
iTernIS ADV
has activated the trends feature for the three patient categories: ADL,
PED and NEO-INF. The information is presented the same way for all categories,
using three graphs on screen that show the evolution of three parameters that can
be chosen by the user (see Fig. 13-1).
The trend menu provides three groups of parameters organized as TREND 1, TREND
2 and TREND 3. This allows having three preset trend options. Section 13.3 Configu -
ration explains how to change the parameters shown in each of these groups.
The different variables are followed up with updates in steps every one minute.
Each new value added to the trend graphs represents the average value of the
parameter during that minute. The curves tracing changes its color when a new
ventilation day begins (date update). This allows to quickly identify the trends that
have been recorded for different days.
The parameters whose trends can be followed up are:
• Peak pressure.
• PEEP.
• Respiratory rate.
• Peak flow.
• Tidal volume.
• Minute volume.
• CTexp (expiratory time constant).
• ETCO
2
(available only if the capnograph is connected).
• Dynamic compliance.
• O
2
concentration.
• Mean pressure.

From this stage on, it is possi -
ble to select one of the three
trend groups or configure these
groups by selecting the para-
meters the user wants for each
of them.
