Diagnostic tools and therapeutic interventions that may influence the integrity of vascular and nonvascular access devices.

Current technology introduces many new vascular and nonvascular devices to the medical field. With the assistance of these devices, patients can be offered many more diagnostic tests and therapeutic treatments that aid in the diagnosis and treatment of diseases. As with any new infusion technology, these devices can be associated with complications attributable to the rapid rate of infusion. This article defines vascular and nonvascular devices; describes diagnostic medication, tests, and treatments that may have an impact on outcome or compromise vascular access; and describes the role of nurses and radiologic technicians in preventing complications related to vascular access.
