3.6.6 Preliminary checks – Alarms
3-28
Ventilator operation check
•
Make sure that the airways pressure increases during the inspiratory
phase.
•
Make sure that the airways limit pressure intervenes (pressometric
operating mode).
•
Make sure that the variation in the set oxygen concentration value (O 2
%) corresponds.
•
Make sure that the ventilator responds properly at parameters variation.
•
Make sure that that the trigger works properly.
•
Make sure that the values set for respiratory frequency and volume are
properly displayed and the pressure, volume and flow curves match the
monitored parameters.
•
Make sure that the alarms intervene properly.
If the O
measured value differs from the set value by more than +/-
2
10%, please repeat the "O
DEMAND.
• If the Vte measured value differs from the set value by more than +/-
20% ( ADULTS parameters ), please go to the "CALIBRATION
PROGRAMS" visualization to perform the calibration of the expiratory
flow sensor (see chapter 3.8 and/or 4.13).
To carry out the preliminary checks relative to ventilator's alarms, you need
to know how the keyboard and the alarms work: please refer to the relative
chapters.
