monitoring a patient chapter 7 7-11
5 Adjust the other stored values, if necessary, to match the lab values.
6 Press the √ key when finished, to enter the adjusted values and return to
display mode.
Or press X to cancel the adjustments.
If the user presses √, the recall key becomes “store” again (and the stored
values are no longer available.) Pressing X leaves the “recall” key active and
keeps the stored values.
Note: When the monitor is turned off, all recalibration adjustments (including the
initial completion of the calibration of all parameters) are lost.
Batteries contained within the CDI System 550
The CDI monitor contains two types of batteries: system batteries and a backup bat-
tery.
System Batteries
The system batteries power the monitor’s date, time and system error code memory.
They are AA lithium batteries. If the battery life is diminished, the system informs the
user during system initialization by providing an error code. The system will normally
allow the user to continue (with certain provisions, such as loss of date and time) by
accepting the condition. The user should contact Terumo CVS Technical Service for
System battery replacement.
Operating on emergency battery power
The backup battery is a 12 volt rechargeable sealed lead/acid battery for backup
power. If power to the monitor is interrupted, the backup battery can power the moni-
tor continuously for up to 25 minutes (if it’s fully charged).
Note:
The Terumo CDI Model 540 Calibrator and the Terumo CDI System 550 Moni-
tor printer will not work while the monitor is on battery power.
When the monitor is working on battery power, a battery symbol appears in the mes-
sage bar, indicating that the battery is in use and showing approximately how much
battery time is left. (See next figure.) After the monitor battery runs down, the user
must plug the monitor into an electrical outlet for at least 8 hours to fully recharge the
battery.
