Abstract
A method includes receiving data regarding a catheter being used with the infusion device. The catheter has a lumen operably coupled to a reservoir of the infusion device and is configured to deliver fluid from the infusion device to a target location of a patient. The method further includes infusing fluid from the reservoir into the lumen of the catheter at a first rate and monitoring pressure via a pressure sensor in communication with the lumen of the catheter. Monitoring the pressure includes acquiring pressure data from the pressure sensor at a first frequency. The method also includes (i) determining whether the monitored pressure exceeds a first threshold, wherein the first threshold is based on the data regarding the catheter; and (ii) decreasing the rate at which the fluid is delivered from the reservoir into the catheter if the monitored pressure is determined to exceed the threshold.
