Abstract
An infusion pump system and method provide concurrent infusion with common line auto flush. The infusion pump system has a first reservoir, a second reservoir, a junction, a mixing chamber, a common line having one end in fluid connection with the mixing chamber and having a terminal fluid delivery end, and an infusion pump. The method includes infusing the first fluid at a first rate along a first flow path; determining a common line flush volume value for the common line; switching to a concurrent infusion mode to drive a combination of the first fluid and the second fluid at the first rate along a second flow path including the common line; monitoring a volume of the combination of the first and second fluids driven at the first rate; and driving the combination of the first and second fluids at a combined rate along the second flow path when the monitored volume is equal to or greater than the common line flush volume value.
