The present invention relates to a method for discharging fluid from a syringe and for attenuating occlusion conditions including actuating the plunger of a syringe within a barrel. The method monitors fluid pressure within the syringe barrel and determines that there is an occlusion when fluid pressure exceeds a predetermined limit. The method actuates the plunger out of the barrel in a predetermined amount in response to the detected occlusion and actuates the syringe plunger within the barrel until a measured fluid pressure within the syringe barrel exceeds another predetermined limit. |
