7.3.7
Overview of alarm limits
7.3.7.1
Ventilation alarms
MV max Upper alarm limit for the expiratory minute volume
MV min Lower alarm limit for the expiratory minute volume
Vt max Upper alarm limit for the expiratory tidal volume
Vt min Lower alarm limit for the expiratory tidal volume
Leakage
Criterion for the “Leakage high” alarm. The percentage describes the
leakage rate which is calculated from the total values (100 x (TVi-TVe)/
TVi).
Plimit
(relative or abso-
lute)
Maximum peak airway pressure
P min Minimum pressure within a breath
PEEP max Upper alarm limit for the measured PEEP
PEEP min Lower alarm limit for the measured PEEP
RR max Upper alarm limit for the measured respiratory rate
RR min Lower alarm limit for the measured respiratory rate
Remark
Depending on the selected configuration, the alarm limit for the
maximum peak airway pressure PLimit can be set manually or it is
linked with the Pinsp setting and adjusted automatically.
7.3.7.2
Gas
+ O
2
max
Upper alarm limit for the inspiratory oxygen concentration. The dif -
ference between the alarm limit and set inspiratory oxygen concen -
tration (O
2
) is maintained if the O
2
value changes. The alarm criterion
can be switched off at the upper end of the adjustment range. In this
case, the “O
2
limit values?” message appears.

min
Lower alarm limit for the inspiratory oxygen concentration. The dif -

tration (O

value changes. The alarm criterion
can be switched off at the lower end of the adjustment range. In this
case, the “O
