Abstract

A system including a tube and a force sensor coupled to a wall of the tube via a restraining element and configured to obtain a value of a tubing force when the tube is deformed by the restraining element. The system includes a processor to determine parameters for fitting a curve including the value of the tubing force, to determine a fluid pressure value for a fluid in the tube based on the parameters for fitting the curve, and to activate an alarm responsive to the fluid pressure value and to the parameters for fitting the curve when an occlusion condition is identified in the tube. The parameters for fitting the curve comprise at least one time-decaying parameter(s) associated to the tubing force. A method for using the system and a non-transitory computer readable medium including instructions to perform the above method are also provided.
