Abstract
A method of detecting an occlusion within a flexible infusion tube by measuring samples indicative of pressures relative to instances in time. Difference values for the samples are created. The difference values are compared to percentages of other difference values. When appropriate, an occlusion signal is generated in response to a comparison of a difference value to a percentage of another difference value.
