9. Alarm signal display area:
o "Good ventilation": all the ventilation parameters calculated are within the appropriate range of values as
defined in the international guidelines
o "Insufficient volume": the volume of air insufflated to the patient is significantly lower than the values given
in the international guidelines
EN
o "Excessive volume": the volume of air insufflated to the patient is significantly higher than the values given
in the international guidelines
o "Low frequency": the ventilation frequency is much significantly than the values given in the international
guidelines
o "High frequency" (for continuous mode): the ventilation frequency is significantly higher than the values
given in the international guidelines
o "Important leakage": the difference calculated between the volume of air/oxygen insufflated and the volume
expired 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
