Feature Definition—Pump Module
Auto-Restart
Part of the system’s Downstream Occlusion Detection system designed to minimize
nuisance, patient-side occlusion alarms. Allows system to automatically continue an infusion
following detection of a patient-side occlusion if downstream pressure falls to an acceptable
level within a 15-second “Checking Line” period. If this feature is enabled, “Checking Line”
function occurs when downstream pressure exceeds pressure limit.
• In Selectable Pressure Mode: Pressure limit
is either user-adjustable or “locked” in system
configuration.
• In Pump Pressure Mode: Pressure limit is a function of flow rate and is automatically
determined by device.
If downstream pressure decreases to a predeterm
ined level, (b
elow 50% pressure limit)
during 15-second “Checking Line” period, infusion automatically continues. If condition is
not cleared within 15 seconds, a “Partial Occlusion - Patient Side”
alarm occurs.
Using the Editor software, the system can b
e configured to allow 0 (zero) to 9 restart
attempts within a rolling 10-minute period. If allowable number of restarts is exceeded or if
feature is set to zero, an “Occluded - Patient Side” alarm occurs when system detects
downstream pressure
that exceeds pressure limit.
NOTE:
Auto-Restart for Anesthesia Mode is set to 9 and is not configurable.
Default Occlusion
Pressur
e
Starting occlusion pressure limit which can be configured by profile in 25 mmHg
increments.
Free Flow
Protection
All BD Alaris Pump Infusion administration sets use a unique clamping device (safety clamp
on the lower fitment) to prevent inadvertent free-flow when administration set is removed
from instrument.
KVO Rate Adjust
Used to select KVO (Keep Vein Open) rate (0.1 to 20 mL/h allowed), which is rate of fluid
flow after an "Infusion Complete" occurs. KVO rate never exceeds infusion rate.
Occlusion Pressure
A complete range of downstream occlusion detection options is provided.
•
Pump mode:
Downstream occlusion alarm threshold is 525 mmHg at flow rates of
30 mL/h or greater. For rates less than 30 mL/h, occlusion pressure is rate-dependent to
ensure rapid response to occlusions.
•
Selectable pressure mode:
Downstream occlusion alarm threshold can be adjusted in
25 mmHg increments, from 50 mmHg up to maximum occlusion pressure of 525 mmHg.

.)
In addition, the system provides fluid-side
occlusion detection.
Secondary Infusions
Dual rate sequential piggyback (secondary) infusions can be infused, with limits, at delivery
rates and volumes independent of primary infusion
parameters. Automatic changeover
occurs to primary infusion parameters
when secondary infusion is complete if a BD Alaris
pump module administration set with a check valve is used.
