Fluid delivery pressure monitoring and control system

Abstract

Examples described herein include: receiving pressure information from a pressure sensor of a syringe, where the syringe is injecting a fluid into a subject at an injection rate; comparing the pressure information to a pressure threshold to determine whether the pressure information satisfies the pressure threshold; and responsive to determining that the pressure information satisfies the pressure threshold, adjusting the injection rate to decrease a pressure of the fluid being injected into the subject.
