Visual messages related to ventilation parameters
Visual messages may appear during ventilation when the ventilation parameters exceed the threshold values and are
persistently outside the ranges given below .
The screen shows the visual messages in the visual signal display area (lower part of the screen) as a message .
The visual messages concern:
•
The tidal volume (Vt):
Visual signal
conditions
Insufficient volume
all the ventilation parameters calculated are within the appropriate range of
values as defined in the international guidelines .
the volume of air insufflated to the patient is significantly lower than the
values given in the international guidelines .
the volume of air insufflated to the patient is significantly higher than the
values given in the international guidelines .
the ventilation frequency is much significantly than the values given in the
international guidelines .
the ventilation frequency is significantly higher than the values given in the
international guidelines .
the difference calculated between the volume of air/oxygen insufflated
and the volume exhaled is too great . This may be because the mask is not
positioned correctly, due to improper intubation (oesophageal intubation) or
because the ventilation circuit is not properly sealed .

Small < 225 mL
Medium < 285 mL
Tall < 350 mL
1-2 years < 45 mL
2-3 years < 55 mL
3-4 years < 70 mL
5-6 years < 90 mL
7-9 years < 115 mL
10-11 years < 140 mL
Solution
Insufflate a volume of air within the
appropriate range as defined in the
international guidelines
