Function
This button activates and deactivates the OLC option as
indicated by the check box to the right. By default, OLC is
enabled.
This button brings up the Kt/V Calculator—a useful tool for
estimating the treatment effectiveness and time required based
on various treatment parameters. (Not available at this time).
Touching the OLC Data button opens the "OLC" subscreen that
provides the actual results of each OLC test.
This button changes functions based on the machine status.
When there is no blood sensed and the blood pump is stopped
or the dialysate lines are on the shunt, touching this button
followed by the CONFIRM key initiates the OLC Self Test.
When blood is sensed, an unscheduled clearance test is
initiated. The manual test takes the place of one of the
scheduled tests entered in the # of Tests button.
This button is used to allow the Access Flow test to be
performed. When it is turned On, the machine will offer to do
the Access Flow test following the next OLC test. If it is
inconvenient to do the test early in the treatment, this button
may be left in the Off position and turned On when it is
convenient. Touch the Manual OLC Test button and press
CONFIRM after turning on the Access Flow to begin the process
right away. When the test is initiated, the operator is guided
through the steps necessary to perform the test.
Warning: To avoid the possibility of significant
blood loss, be sure that the connections are well
secured after disconnecting and reconnecting the
bloodlines.
The patient's, urea-distribution volume (in liters) is entered here.
This value should be determined using urea-kinetic values.
Anthropometric formulae may give different results than
kinetically calculated urea-distribution volume.
The prescribed target single-pool value, ranging from 0.40 to
2.50, is entered in this button. This value is reset to the default
value when the New Tx key is pressed. The default value may
be changed in Service Mode.
