Froth detection system and method

Abstract

An infusion system includes a pump, a fluid delivery line, at least one sensor, a processor, and a memory. The fluid delivery line is connected to the pump for delivering fluid. The at least one sensor is connected to the fluid delivery line for emitting and receiving signals to detect whether there is air in the fluid delivery line. The processor is in electronic communication with the pump and the at least one sensor. The memory is in electronic communication with the processor. The memory comprises programming code for execution by the processor. The programming code is configured to determine a percentage of the air within an observed volume of the fluid delivery line.
