P/N 53063-50, Manual Revision: B Automatic Operation: Cell Salvage
5-17
EMERGENCY
Option
The emergency option is available for those situations in which the speed at
which blood is available for return to the patient is the most important factor. The
emergency option is accessible from the AUTOMATIC mode when the machine
is in the FILL,WASH, EMPTY, CONC, and RETURN functions. This option cannot
be entered from the STANDBY or stop state.
Note: The EMERGENCY option is not available for use with the 70 mL bowl
The emergency option will process blood continuously through the FILL, WASH,
and EMPTY cycles until the air detector sees air for the first time in the FILL
sequence, meaning the reservoir is empty. Upon seeing an air detected message
in the FILL sequence, the CS5+ will switch back to the AUTOMATIC mode and
the machine will enter STANDBY. The operator may also choose to CONCentrate
or RETURN cells to the reservoir while in the emergency option.
Parameters in EMERGENCY Option
The preset parameters in the EMERGENCY mode are:
*If the air/plasma interface has not yet been detected by the optics, the fill rate
will remain at 400 ml/min until this event occurs, at which time it will increase
to 800 ml/min.
Note: The line sensor will not be active during the emergency option.
Warning: Red cells may be lost into the waste bag as a result of choosing the
emergency option.
Entering the EMERGENCY Option
To enter the EMERGENCY Option from the AUTOMATIC mode, press the MODE
key twice within 2 seconds. The operator will then be prompted to confirm this
choice by pressing the YES key within 5 seconds. If the YES key is not pressed
within 5 seconds, or the NO key is pressed, the CS5+ will revert back to the
AUTOMATIC mode. While waiting for confirmation, the pump speed will slow
to 25 ml/minute.
