Official Description

Bioimpedance spectroscopy (BIS), measuring 100 frequencies or greater, direct measurement of extracellular fluid differences between the limbs

Common Language Description

Bioimpedance spectroscopy (BIS) is an advanced diagnostic technology utilized primarily for the early detection and management of lymphedema, particularly in patients who have undergone mastectomy or pelvic surgery due to malignancies. This innovative method is capable of identifying variations in extracellular fluid levels between different limbs, often before any visible swelling occurs or before the patient experiences symptoms typically associated with early lymphedema. Although lymphedema itself cannot be entirely prevented, the ability to diagnose it at an early stage enables healthcare providers to initiate appropriate therapeutic interventions aimed at mitigating the negative consequences associated with this condition. The BIS technique employs a non-invasive approach by applying a low-level electric current to the body, which measures the resistance encountered as the current passes through various tissues. This resistance, or impedance, is then analyzed to determine the differences in extracellular fluid volumes between the limbs. For the assessment of fluid levels in the upper extremities, two electrodes are strategically placed on each hand, along with a set on one foot. Conversely, when evaluating the lower extremities, electrodes are positioned on each foot and one hand. Once the BIS device is activated, it captures the extracellular fluid measurements from each limb, allowing for a comparative analysis of impedance values. The physician subsequently reviews these measurements in conjunction with any prior BIS data to ascertain whether the findings suggest the presence of early lymphedema, thereby facilitating timely and effective treatment options to alleviate the potential adverse effects of this condition.

1. Indications

The procedure of bioimpedance spectroscopy (BIS) is indicated for the following conditions:

Early Detection of Lymphedema - BIS is utilized to identify early signs of lymphedema in patients who have undergone mastectomy or pelvic surgery for malignancy.
Monitoring Fluid Levels - The procedure is indicated for monitoring extracellular fluid differences between limbs to assess the progression or resolution of lymphedema.

2. Procedure

The procedure for bioimpedance spectroscopy (BIS) involves several key steps to accurately measure extracellular fluid differences between limbs:

Electrode Placement - To begin the procedure, a set of two electrodes is placed on each hand and one set is positioned on one of the feet for measuring extracellular fluid in the upper extremity. For the lower extremities, a set of electrodes is placed on each foot and another set on one of the hands. This strategic placement is crucial for obtaining accurate measurements of fluid levels in the respective limbs.
Activation of the BIS Device - Once the electrodes are securely attached, the BIS device is activated. The device generates a low-level electric current that passes through the tissues of the limbs, allowing for the measurement of impedance, which reflects the resistance encountered by the current.
Measurement and Comparison - The BIS device measures the extracellular fluid in each limb and calculates the impedance ratios. These measurements are then displayed, providing a clear comparison of extracellular fluid levels between the upper and lower extremities. The physician reviews these impedance measurements alongside any previously obtained BIS data to evaluate changes over time.
Assessment and Treatment Decision - After analyzing the measurements, the physician determines whether the results indicate early lymphedema. If early signs are present, the physician can prescribe appropriate therapies aimed at reducing the adverse effects associated with lymphedema.

3. Post-Procedure

Post-procedure care following bioimpedance spectroscopy (BIS) typically involves monitoring the patient for any immediate reactions to the electrode placement or the procedure itself. Patients may be advised to maintain regular follow-up appointments to track any changes in extracellular fluid levels over time. Additionally, if early lymphedema is detected, the physician will discuss the recommended therapeutic interventions, which may include physical therapy, compression garments, or other management strategies to address the condition effectively. Continuous assessment and timely intervention are essential to minimize the long-term effects of lymphedema.
