Pulse Profile
The Pulse Rate profile is used to create an oscillating
infusion or withdrawal profile that varies between a
starting flow rate and a second rate that can be either or
higher or lower than the start rate. The flow rate is
constant within each segment of the pulsed flow profile
and the user defines the total number of repetitions
(pulses) for the oscillating pattern. Each segment of the
profile must be set to run for either a specific length of
time or to deliver a set volume.

Pulse Rate Pump Operation Profile
When creating or editing a Pulse Rate profile, you will
define four primary operating parameters:
•
The Flow Mode defining the direction of flow:
forward or reverse
•
The Flow Rate to be used at each level of the
pulsed profile within the pumping cycle
•
The length of Time that each segment of the profile
will run or the specific Volume to be
infused/withdrawn during each segment of the
profile
•
The Number of Pulses (repetitions) that will be
executed during the pumping cycle
During a Pulse Rate profile, the KDS Allegro Peristaltic
Pump calculates a series of equal length pumping stages
at two user-defined flow rates: a starting rate and a
“pulse” rate. You enter the Number of Pulses (repetitions)
that you want to use, along with how you want the system
to calculate the length of each stage — by time or by
volume pumped. A Pulse Rate profile can be applied to
pulses that are higher in rate or lower in rate than the
starting flow rate.
When creating or editing a Pulse Rate profile, you can set
the rate in L, ml, µl or nl units of volume using sec, min or
hr as the units of time. The system automatically
calculates a minimum and maximum flow rate based on
the syringe selected or custom-defined. The min/max
values are made available as button selection options on
the Set Pulse Rates screens.
