Sapphire Infusion Pump User Manual 271
Infusion under high backpressure conditions (for example, when using catheters, or
other restricting administration set components) may cause the accuracy of the pump
flow delivery to deviate from the accuracy stated for normal conditions.
The pump is designed to accommodate the delivery of infusions under backpressure
conditions with an expected deviation in accuracy of +5% to -5% (
Note
: In high
backpressure conditions, such as with a 26G PICC line infusing at 100mL/h, additional
under delivery may occur).
In the Sapphire pump, as in all infusion systems external factors may cause fluctuations
in rate accuracy. Conditions that can cause flow fluctuations include:
•
Position of the infusion container height (any deviation from 50 cm above the
pump)
•
Fluid characteristics that deviate from water-like characteristics, such as density,
viscosity and homogeneity
•
Positive and negative pressure, including back pressure
•
Environmental temperature above or below 25°C and barometric pressure above
or below 101kPa
For example:
•
A change of ±25 cm in the fluid level above the pump may result in deviation in
accuracy of ±1%
•
Using sets with PAV may result in deviation in accuracy of -6%
When using accessories where the container height deviates from
50 cm above the pump, there may be deviations in pump accuracy
(e.g., PCA Lockboxes, Large Backpack and EBP).
