Button
Function
The
Rate
button displays the rate at which heparin is dispensed during
treatment. It can be set from 0.0 to 9.9 ml/hour.
The
Infusion Time
button displays the amount of time in hours and
minutes that the heparin pump will deliver heparin. The program time can
be set from 0 to 9:59. For the heparin pump to stop at a desired time
automatically, the operator must set an Infusion Time. When the heparin
pump is On, this time will count down to 0:00 and stop heparin delivery.
Infusion Time can be set to zero only when the heparin pump is Off.
The
Total Infused
button displays the current total amount of heparin
delivered up to 45.7 ml (including the bolus). Total Infused can be reset to
0 with the numeric keypad or arrow keys and pressing the
CONFIRM
key
when the Heparin pump is Off.
The amount of heparin to be delivered as a bolus infusion is entered here.
The heparin pump delivers the bolus infusion at a rate of about 0.17
ml/sec (1 ml/6 seconds) for a 10 cc syringe. This amount can be set from
0.0 to 9.9 ml. During delivery, the Bolus amount is added to the amount
shown in the
Total Infused
button.
The
Syringe
button opens a menu listing various syringe types. The
operator selects the syringe matching the one that will be used during
treatment.
The
Infuse Bolus
button activates the heparin delivery system to
administer the amount of heparin displayed in the
Bolus
button. Once
activated, the actual delivery is accomplished by pressing
CONFIRM
.
Afterwards, the heparin pump will infuse heparin at the rate displayed in
the Rate button.
Touching the
Load Syringe
button, followed by the
CONFIRM
key, fully
retracts the heparin pump carriage to allow the mounting of the syringe in
the pump. Pressing the
Escape
key will stop the travel of the carriage.
The
Heparin Prime
button initiates a process to fill the Heparin line. Once
a syringe is mounted in the pump, press the
Heparin Prime
button,
followed by the
CONFIRM
key. The syringe plunger is pushed upward
into the barrel while the
CONFIRM
key is pressed.
The optional
Heparin Dwell
button (enabled in Service Mode) acts as a
five minute timer after a manual heparin bolus is administered. To use the
timer, select the
Heparin Dwell
button and press the
CONFIRM
key. This
will cause the optional ‘Traffic Light Status Beacon’ on the IV pole to flash
yellow at half-second intervals for five minutes while the heparin is
dwelling. After the five minutes has elapsed, the Status Box will display
the message, “Heparin Dwell Complete,” and the ‘Traffic Light Status
Beacon’ on the IV pole will turn green and continue to flash until the
operator presses the
RESET
key.
Warning!
If no time is set in the
Infusion Time
button and the heparin pump is turned on,
it will run at the selected rate until the syringe is empty or the heparin pump is turned off.
The heparin pump should be monitored to verify the intended infusion during treatment.
