Occlusion Limit
This feature lets the user change the occlusion pressure limit to 75, 100, 200,
300, 400, or 500 mmHg. At rates of 400 mL/hr and higher, the pressure
setting is automatically increased to 400 mmHg. Occlusion pressure is a
threshold value.
For Example
: If the occlusion pressure is set to 300 mmHg, the pump will
infuse at the lowest pressure possible but will alarm if the
pressure required to infuse the IV fluid rises above the 300
mmHg value.
A gravity infusion of D5W with the IV container 3 feet above the IV site is
equivalent to approximately 70 mmHg.
The occlusion warning feature is optional. The occlusion warning feature
gives an audible warning (3 beeps) and a visual indication in the LED
display to let the user know an occlusion is occuring downstream from the
pump. This warning occurs 5 times at 5-second intervals before alarming
“Occlusion.” This feature is designed to alert the clinician of downstream
resistance before an alarm occurs which stops the infusion.
Caution:
The higher the pressure limit, the less sensitive the pump is to
changes in fluid resistance which may be caused by positional
IV’s or infiltrations. High pressure limits can increase the
severity of an infiltration without an alarm condition.
