Activation of special Kangaroo Mode alarms
During Kangaroo Mode, the skin (and central) temperature of
the infant is frequently found to rise. However, in some cases,
the infant becomes cooler. Consequently, the infant's central or
skin temperature must be regularly monitored. In order to
perform this monitoring with as little nuisance alarms as
possible to mother/father and infant, Caleo allows to activate
special Kangaroo Mode alarms during operation in Kangaroo
Mode. These alarms are set in the configuration. The following
alarm limits are set:
– Lower alarm limit for the skin temperature
(Skin 1; T1) = Skin T1 min.
– Lower alarm limit for the peripheral temperature
(Skin 2; T2) = Skin T2 min.
– Lower alarm limit for the difference
between T1 and T2 = ΔT min.
– Upper alarm limit for the difference
between T1 and T2 = ΔT max.
These kangaroo alarms have the following significance:
Skin T1 min.:
The alarm is triggered as soon as the (central) skin
temperature (T1, yellow skin temperature sensor) falls below
this alarm threshold.
Skin T2 min.:
The Skin T2 min. alarm is triggered as soon as the peripheral
skin temperature (T2, white temperature sensor) falls below
this alarm threshold.
ΔT min.:
This alarm is triggered if the difference between Skin T1 and
Skin T2 is less than this alarm threshold (risk of hyperthermia).
