ImpediMed L-Dex XCA
The ImpediMed L-Dex XCA has been cleared for use in the USA by the FDA for monitoring fluid accumulation in patients with lymphedema. This product is not yet cleared for use in Canada. Please contact us for availability in other countries.

Lymphedema develops slowly over time. It is recognized that earlier diagnosis, leading to earlier intervention, is the best management strategy for this condition. The L-Dex XCA is designed for improving the earlier detection and monitoring of changes in extracellular fluid levels for patients with unilateral lymphedema of the arms.

The L-Dex XCA is a bioelectrical impedance analysis (BIA) device, specifically designed for the accurate monitoring of extra cellular fluid level in the arms. The instrument measures impedance and phase angle of the affected and the unaffected body limbs in subjects who have secondary lymphedema. These measurements are then used to calculate the Lymphedema Index or L-Dex™ ratio. L-Dex is the trademark and family name for devices that will produce these types of lymphedema results. ImpediMed provides Lymphedema analysis software for storing subject details and data points for reports that can display results graphically over time (e.g. % change in ratio from baseline).

Benefits of the L-Dex XCA
• Earlier Detection: Clinical studies have proven from 1 to 4 months earlier detection1
• Relevant measurements: Determines extra cellular fluid levels, not total limb volumes. Better for demonstrating the improvements associated with treatment
• Consistent and Precise: A standardized objective result is offered by the XCA. Subjective tape measurements are often more susceptible to operator variations
• Value: Maximizes time with the patient - set up and reading times with the L-Dex XCA takes around 3 to 5 minutes. Allows therapist more time to treat patients
• Reduced patient anxiety: Measurements of both arms before surgery as a baseline with continued regular monitoring can help manage anxiety for patients
• Quality of life: It is not possible to predict who will get lymphedema, but recognizing it early and treating it promptly is the best way to manage the condition.

Validation
Prior to its release, methods of assessing lymphedematous limbs included circumferential measurements of limb size and water immersion. Both these methods fail to produce results reflecting the hydrostasis of the limb. Thus, there was no good reference method for the precise quantification of peripheral lymphedema. The bioelectrical impedance analysis (BIA) technique has, however, been demonstrated to be approximately four-fold more sensitive than the commonly used circumferential method for assessing the onset of lymphedema.

Applications
• University & Hospital research, Lymphedema societies
• Primary care physician, Nurses, Physiotherapists, Lymphedema Massage therapists
• Drug developments – assessing therapy response.
