Nephrology
Develop effective dialysis treatment options
Australian Register of Therapeutic Goods (ARTG) #207297
Why is body composition analysis an effective tool for dialysis programs?
InBody devices take the guesswork out of dialysis treatments to help monitor the most effective treatment options for the patient and obtain the ideal goal weight.
In 60 seconds, professionals can use the InBody to:
Obtain objective fluid measures to guide goal weight management
Assess muscle and fat mass to make nutritional changes
Evaluate segmental fluid imbalances to identify circulation issues
Validation Studies
Importance Of Fluid Balance
“Overhydration as assessed by ECW/TBW is prevalent in adult PD patients, and is associated with loss of residual renal function, inflammation, malnutrition and hypertension.”
Fan et al., 2012
Benefits Of Phase Angle
“BIA is an attractive method because it is safe, easy to use, noninvasive, and relatively low cost. BIA-derived parameters have therefore been investigated as novel nutritional markers, especially in patients with ESRD who are receiving maintenance hemodialysis.”
Shin et al, 2017
Benefits Of BIA With Goal Weight
“MF-BIA was superior…in the evaluation of body water distribution in end-stage renal disease and other clinical disorders of fluid volume and/or distribution and validation for assessment of body water in HD patients.”
Lee et al., 2001
Muscle-Fat Analysis
Balance muscle & fat development per individual needs.
Segmental ECW/TBW Water Analysis
Avoid interdialytic complications from fluid accumulation
Interdialytic weight gain can be masked by the loss of muscle and fat mass. Professionals rely on the indirect practice of pitting edema to identify changes in fluid levels. Objective measures of body water help identify water retention as a form of weight change independent of changes in muscle or fat mass.
Nephrologists can use Segmental ECW/TBW Analysis to distinguish fluid accumulation from muscle and fat composition, allowing for more precise tracking of fluid overload independent of nutritional status. This will allow physicians to set proper goal weights, confirm fluid volumes post-dialysis, and make more appropriate adjustments of patient goal weights long-term.
Why do nephrologists trust InBody?
Multiple frequencies
InBody uses multiple frequencies to provide a precise analysis.
By using several different frequencies, more resistance values are attained, providing more information during the analysis. The InBody 970 uses 8 frequencies to measure each segment of the body, providing a total of 30 separate impedance values.
Electrical currents have a different penetration force depending on the frequency. Low frequencies measure the water outside the cell (extracellular water), as they are unable to penetrate the cell wall. Higher frequencies will measure the water content inside the cell (intracellular water) because it penetrates the cell wall.
By using a diverse set of frequencies, the InBody can measure water contents inside and outside the cell separately. Controlling the path of high frequency waves is very difficult. This technical know-how is an InBody specific specialty and has been accumulated over many years of experience in the field.
8-Point Tactile Electrode System
When measuring impedance through any type of electrode, contact resistance occurs. It is important to control the contact resistance, in order to correctly measure the resistance in the body.
The 8-point tactile method separates the current and voltage starting point. This measurement always begins at a fixed point in the wrists and ankles. This is advantageous, as the contact resistance from the skin has been removed. This creates the high precision of reproducing the results that InBody are renowned for.
Measuring the body parts individually
The technical term for this is Direct Segmental Multi-frequency Bioelectrical Impedance Analysis (DSM-BIA). It separately measures the impedance (resistance to alternating electric currents) of the trunk, arms, and legs of our body.
This new measurement concept measures the resistance of the cross point of two flows and takes the resistance values of the arms, legs and the body trunk.
Why is this important? The human body is composed of five cylinders: the arms, legs and trunk. With the technology of the InBody, the trunk is directly measured. The trunk is occupied by various internal organs and its metabolic characteristics are different from the other parts of the body. Although difficult, it is important to precisely and directly measure the trunk, since the trunk has very low resistance compared to the arms and legs.
No Statistical Data Needed
InBody is the only BIA device that measures body composition without relying on age and gender to make assumptions about your measurement. The results are extremely precise, and as unique as the person standing on the device.
InBody provides individualised result for better tracking of progress to help you achieve your goals. You can change your age and/or gender on an InBody device and your measurement will not change because you have not changed.
This is one of the underpinning reasons why InBody is used around the world in extensive studies and utilised by top sports people, medical institutions and NASA.
