InBody devices are non-invasive and tests are completed in less than 60 seconds. InBody data can be used to fluctuations and fine tune the process of bringing dialysis patients to the appropriate dry weight. InBody devices can also be used to determine where a patient is holding excess water and track fluid movement. This accurate, reproducible information doesn’t rely on empirical data and therefore, reflects the patient.

Biometric data is gathered by InBody’s four core technologies:

Multi-frequency Measurements

Multi-frequency Measurements are able to measure extracellular water (ECW) and intracellular water (ICW), providing an accurate and quantitative measure of total body water.

Direct Segmental Measurement

Direct Segmental Measurement divides the body into five separate cylinders and measures the impedance for each segment.

8-Point Tactile System

The 8-Point Tactile System with thumb electrodes offers reliable reproducibility by ensuring that tests are always beginning at the same anatomical starting points.

No need for empirical estimations

These technologies combined eliminate any need for empirical data(assumptions for body composition based on factors like age, gender or ethnicity).

What is nephrology?

The field of nephrology focuses largely on body water and dialysis. Dialysis is a treatment that filters the blood of all excess fluid, toxins, and waste and is prescribed when the kidneys can no longer do those processes on their own. Dialysis treatments must be performed multiple times a week, for hours at a time, for the rest of the patient’s life.

Once a patient has been prescribed dialysis by a nephrologist, specialists must calculate how much water to remove from the body in order to achieve the patient’s dry weight. Ideally, this weight allows normal blood pressure to be maintained without using antihypertensive medication.

Validation Study

In a group of patients with OSA in Hemodialysis, the effects of both compression stockings (CS) and continuous positive airway pressure (CPAP) were assessed to see improvements in neck circumference, Apnea-hypopnea index (AHI), and fluid retention in the body. After each intervention, it was seen that CPAP displayed superior performance to the CS. However, CS did reduce AHI by avoiding fluid retention in the legs, keeping it in the intracellular compartment of the trunk. This emphasizes a feasible alternative treatment for hemodialysis patients with OSA.
