APPENDIX 2
TIME NEEDED TO SIGNAL AN OCCLUSION
The time needed to signal an occlusion is the interval between the beginning
of the occlusion condition and the recognition of the condition by the pump.
This value depends on the ow rate, because the lower the ow rate, the lon-
ger will be the time needed by the pump to recognise the occlusion condition.
The values given here consider the time needed jointly by the pump and the
reservoir to signal the occlusion.

• The time needed to signal an occlusion is dependant on the ow rate, be-
cause the lower the ow rate, the longer will be the time needed by the pump
to activate the occlusion alarm.
• The time needed to signal the occlusion can increase if there is air in the
line, if you are using catheters, lters and extension tubes of other dimen-
sions, or in an elastic material, or when the line from the pump is connected
to other devices.
• For patients who could suffer severe harm if there is an interruption in the
administration of the drug by the pump, arrangements must be made for them
to be under the strict supervision of a doctor who can take any immediate
corrective action required.
