Zone Insertion Method™ (ZIM™)

The Zone Insertion Method™ (ZIM™) is a standardized approach to upper arm ultrasound assessment to provide consistent site selection focused on an Ideal Zone for device insertion.

This Ideal Zone accounts for the principles of vascular access that reduce risk from site selection and catheter dwell. Areas of flexion, vessel size to catheter size, and risk of inadvertent nerve and arterial puncture are all factors accounted for in the ZIM assessment. The ZIM also standardizes teaching for upper arm device insertion for PICCS and Midlines. It provides for reduced trauma, easier and more efficient vessel access with the modified seldinger technique (MST). The most important factor in vascular access to reduce harm and improve outcomes is to minimize vessel trauma. This means one attempt access, out of an area flexion in the largest, straightest vessel possible. If a clinician can consistently reduce trauma and achieve one attempt access than outcomes will improve, satisfaction will be higher, and costs will be reduced. Additionally, performance can be measured compared to the principles of the ZIM and this can provide objective feedback to clinical staff on how to improve results. The ZIM is a systematic clinical tool for Modern Vascular Access.
