Power Interruption
Note
If an uninterruptible power supply or battery backup is not used to power the ACIST RXi
system, and a power interruption for any length of time is experienced, the RXi system
will power on once power is resumed if the power on/o switch remains in the on
position. If a Navvus MicroCatheter is present during the power on, a new case is also
initiated. For this reason, it is necessary to ip the switch to the o position and remove
the catheter once a power interruption occurs. Turning power o ends the case.
Auditory and visual alarming and information signals are disabled while the system is
powered down. Upon resumption of power, if a defective microcatheter with a broken
ber optic cable remains connected to the system, the system resumes alarming.
Following a power interruption (no matter how brief), if the ACIST RXi
System has been set up as a mobile device, aortic pressure must be zeroed.
Refer to page 72 for instructions on performing this procedure. If it has
been set up as a stationary device, it does not need to be zeroed. For all ACIST
RXi Systems, signals must be equalized following a power interruption. See
page 37 for instructions on equalizing.
All data from previous cases is saved. However, if a case recording was
in progress when the power was interrupted, this data is lost. Any saved
recordings for the case are still saved. In addition, if a Patient ID and/or Vessel
ID had been entered, these settings will have been lost and will need to be re-
entered. If the case summary was exported to a USB memory device, this data
will be saved, along with the Patient ID.
