Abstract
The invention relates to a method and system for monitoring pressure conditions in the fluid pressure upstream and downstream of an intravenous fluid administration system and to detect upstream and/or downstream occlusions. In addition, the invention incorporates a method for detecting pressure conditions at an upstream or downstream detector across the wall of the tubing to identify upstream or downstream occlusions, respectively. The present invention also relates to a process for determining the fluid pressure in a fluid tube across the tube wall where the normal tube force changes over time, and more particularly, using a normalization process to eliminate changes in the tubing resilience.
