A Non-Invasive, Fluid-Specific Break Through: The Lymphedema Index (L-Dex)
ImpediMed’s L-Dex technology utilizes the characteristics of frequency dependent current flow to quantify changes in extracellular fluid in the patient’s limb. These changes can assist the surgeon or oncologist in clinically assessing early signs of lymphedema. The L-Dex technology is specific for extracellular fluid and is unaffected by changes in the patient’s weight due to a change in fat mass or muscle mass. As fluid accumulates, the L-Dex value increases on the scale. The L-Dex number provides an instant tool for assisting in the clinical assessment of lymphedema progression as well as an easy way to track change in the patient over time.
The L-Dex U400 is a bioimpedance spectroscopy (BIS) device designed to aid in the assessment of unilateral lymphedema in arms. This easy-to-use device provides a rapid, non-invasive and cost effective measurement designed to monitor the fluid content in the limbs of people who suffer from, or are at risk of, lymphedema. The instrument also enables long-term patient monitoring and provides reports to support clinical and research practices.
The L-Dex U400 will store more than 1000 data records, which can be analyzed directly on the device or downloaded via an Ethernet connection to the supplied Impsoft® Unilateral Lymphedema Analysis Software running on a Windows PC.
Ease of Use
- Enter patient demographics in L-Dex software.
- Clean electrode sites and place 3 Dual-Tab electrodes on patient.
- Attach color-coded leads and perform measurements following on-screen instructions.
- Results will appear on the U400 screen and can be uploaded to PC software for storage or additional analysis.
Lymphedema: Early Detection and Treatment are Critical.
Recognizing lymphedema early and treating it promptly is the best way to manage the condition. Without appropriate and timely treatment, lymphedema can lead to pain, recurrent infection, reduced mobility and impaired function. ImpediMed has developed bioimpedance devices that, through the measurement of subclinical changes in extracellular fluid (ECF), detect lymphedema up to 10 months earlier than current methods. The L-Dex U400 has been designed specifically to aid in the preoperative clinical assessment and monitoring of lymphedema in the arms.
Note: L-Dex values that lie outside the normal range may indicate the early signs of lymphedema and values that have changed +10 L-Dex units from baseline may also indicate early lymphedema. The L-Dex scale is a tool to assist in the clinical assessment of lymphedema by a medical provider.
