The term electric bioimpedance refers to a technique to measure impedance in a non-biological environment and the term “bio” refers to biology hence the term bio-impedance.
The bioimpedance has to do with the study of specific electric properties of a biological environment.
BIA stands for electric Bioimpedance Analysis which is commonly used to refer to this technique.
The multi frequency bioimpedance is the only technique that covers each and every one of the body compartments, besides, it has the advantage of being a simple, painless, non-invasive- low cost technique which provides immediate results.
Other non-invasive techniques to assess the overall body balance of an individual:
The design of a direct plug of single use measurement device, cordless without any electrodes, a system we have patented can explain it by means of the comparison described as follows.
There are three ways of taking the measurements:
The first BIA devices were manufactured over the concept of single frequency at 50 kHz.
En multifrecuencias, los dispositivos tienen al menos 3 frecuencias entre 1 y 1000 kHz.
They allow you to obtain more advanced information about the Wellbeing and physical condition of the individual taking into account not just their fat mass and the non-fat mass but also an array of physiological data such as the intra and extracellular water, IR (Impedance Relationship), PhA (Phase Angle), active cellular mass, metabolic proteins, bone mineral content, muscle – skeletal mass of the extremities ... which are true physiological indicators.
Nowadays there are two different approaches to interpret the results obtained from the chosen electric parameters (Impedance, phase angle, resistance, reactance)
The very principle of these devices is simple.
It is based on the following premise, in any kind of individual their hydration is constant for example, to 73,3% of their non-fat mass) and the other compartments are only defined from their coefficients based on constants.
Therefore, these devices can work on a single algorithm based on the calculation of the water. For example: non-fat mass = (total water * 0,733), proteins = (non-fat mass * 0,198) etc.
Based on the water level and weight of the individual a single spreadsheet is enough to obtain other body compartments. They are defined as the deductive type
For example two of the “essential algorithms” which are the non-fat mass algorithm and of total water allow to obtain the real hydration rate of the mass excluding the fat, a very important piece of data because it will be able to determine if the individual has a normal level of hydration or if it is insufficient or if he is over hydrated.
The other body compartments are interpreted based on the complementary algorithms or by means of simple mathematical operations. These devices are defined as the non-deductive type.
Everyone is different, all our devices provide multi-algorithmic interpretations. The interpretation of the impedance values obtained across the range of frequencies allows an individualized representation of the body composition of a measured individual.
The software is installed in the hard drive disc of the device.
The software is installed in remote servers
The cell phase shift measurement only takes a few microseconds. The resistance and the distance to carry, through the cables, the measurement to the measurement circuit causes a message reception time that will inevitably be added to the initial phase time (DT). Therefore, the result obtained will no longer be the initial result.
