Instructions for use Zeus Infinity Empowered SW 2.n
Infusion
For every two Module DPS syringe pumps, a pa-
rameter field can be displayed containing:
– Pump number
– Drug names
– V
tot mL (volume administered up to that point in
time)
– T
rest min (time until the syringe is empty)
z Touch parameter field.
The current alarm limit setting appears.
Display of the flow tubes
A The current flows of the anesthetic agent, e.g.,
Iso, and of the gases O2, Air, and N2O are dis-
played.
B The status display indicates the status of gas
delivery (fresh-gas control mode, closed sys-
tem, current fresh-gas flows, etc.).
C The O
2 uptake display is used for leakage de-
tection when operating in a closed system. If the
device is in Uptake mode, the complete O
2 up-
take of the patient is displayed.
O2 uptake / Uptake monitoring
Zeus IE uses the Brody formula for uptake monitor-
ing:
O
2 uptake = 10 x KG
3/4
KG is based on the body weight set for the patient.
Uptake monitoring is first activated 3 min after
achieving the mode.
The theoretically calculated O
2 uptake is compared
to the measured O
2 uptake in the system. If the
measured value exceeds the calculated value, the
background of the O2 uptake display begins to flash
in yellow.
The user can set the sensitivity of the alarm using
the Brody factor, see page 164.
z Touch the display of the O
2 uptake.
The Alarms > Ventilation dialog window opens,
seepage164. The Brody-Factor button is yellow
and can be adjusted.
z Touch the display of the flow tubes.
The Trends/Data > Current flows dialog window
appears.
