Introduction and Start Up
P7000, P6000, TIVA, TCI & TIVA 11/106 1000SM00012 Issue 8
FAST START
is a configurable feature of the Model P7000 syringe pump, enabled/disabled via the
CONFIGURATION
menu, access code
251
. When enabled,
FAST START
automatically reduces the 'mechanical slack' between the plunger
mechanism and syringe at the start of an infusion. The mechanical slack is a very small gap (barely visible) due to the type
of syringe and mechanics of the pump, between the back of the syringe plunger and the plunger drive mechanism at the
start of an infusion.
How FAST START works
At the start of an infusion, the pump starts at a faster rate for a short period of time. This action minimises the start up
delay but may not eliminate it completely.
Notes:
1) The pump can be heard to pump faster than the set infusion rate and can also be felt if a hand is rested on the pump
at the start of an infusion.
2) The faster rate is 50% of the maximum syringe rate, syringe rate ranges are listed in Appendix A, 'Specifications'.
Purge recommendation:
Even with
FAST START
available, it is still recommended to perform a
PURGE
with the pump before
connecting the extension set to the patient and starting the infusion, especially at low flow rates i.e. below 5ml/h.
Clinical benefits of FAST START

The fluid is delivered to the patient much sooner than if fast start was not available

The delay in delivering the drugs following the changes of syringes is reduced greatly
Fast Start Feature (Model P7000 only)
BACKOFF
is a configurable feature, enabled/disabled via the
CONFIGURATION
menu, access code
251
. When enabled,
BACKOFF
is automatically activated every time an occlusion occurs. The pump action reverses and pumps backwards to
release the pressure which has built up in the infusion system. This minimises the post occlusion bolus.
How BACKOFF works
When an occlusion occurs, the pump continues pumping until the pressure alarm level is reached and the pump stops.
Note that an occlusion can be due to a clamp or stopcock being left closed, kinked line, infiltration etc. During this time,
a bolus volume of fluid builds up and is stored between the occlusion and the syringe, because it is unable to be infused
into the patient. BACKOFF prevents the accumulated volume of fluid from being released into the patient as a post
occlusion bolus.
Following an occlusion alarm:

Pumping mechanism reverses, it pumps backwards

Accumulated volume of fluid (post occlusion volume) is ‘taken back’ into the syringe and not infused into the
patient

Post occlusion volume is deducted from the
VOLUME
(Volume Infused) value shown on the Display

Post occlusion volume is deducted from the infused value in the 24H LOG as this volume has not been infused into
the patient

BACKOFF time and date is recorded in the
EVENT LOG
Clinical benefits of BACKOFF

Reduces the pressure in the extension set due to the plunger of the syringe moving backwards

Removes the post occlusion volume of fluid from the system, it is not delivered to the patient as a bolus on
removal of the occlusion. This prevents the patient from receiving an unintentional and unnecessary bolus
