Monitor, Extracellular Fluid, Lymphedema, Extremity
The Extracellular Fluid Lymphedema Monitor for Extremities (product code OBH) is a non-invasive cardiovascular device that measures bioimpedance in affected and unaffected opposite extremities to periodically monitor extracellular fluid levels in patients previously diagnosed with unilateral lymphedema. By comparing impedance differences between opposing limbs, clinicians can track disease progression and guide therapy. This device is FDA Class 2, requiring 510(k) clearance and compliance with general and special controls under regulation 870.2770 in the Cardiovascular specialty. It carries no implant or life-sustaining flags.
