  • Monitoring change of body fluids during physical exercise using bioimpedance spectroscopy

    During physical exercise body muscles are activated and heat is generated. In intensive physical activity, heat will be released by sweating to protect the body of overheating. Sweating and convection implies a water loss which can lead to dehydration. To avoid health problems as a result of dehydration, the body water content can be monitored to detect changes early in order to rehydrate in time. Bioimpedance Spectroscopy (BIS) is a comfortable measurement method to monitor the body composition under controlled conditions, that is used for different applications, like monitoring dialysis. Unfortunately, the physiological changes due to sportive activities can influence the BIS and complicate the measurement. In this article, a study is presented in which the fluid content of five test persons is monitored during physical exercise, whereas all test persons did not drink anything before and during sport. During training not only the body composition was measured using a BIS device but also the skin temperature was monitored with an infrared camera. As a result, it could be shown that such a combination of measurement systems allow to use BIS devices also during sport as significant monitoring systems for detecting a person's body fluid loss.

  • Supine vs. elevated supine postures: Comparative effects on blood ejection and perfusion

    The comparative effects on blood ejection and perfusion between supine and elevated supine postures with upper body elevations were investigated in this study. Blood ejection and perfusion were measured by electrical bioimpedance and laser Doppler flowmetry techniques respectively in normal human subjects. Using hardware and software, electrical bioimpedance based blood ejection from heart were calculated in different supine postures (normal and elevated). Skin blood perfusions were also measured by laser Doppler flowmetry technique in all cases. At first, data recordings were performed in normal supine posture (upper body elevated by 0o). Data recordings were done also when upper body elevations were sequentially increased to 15o, 30o, and 45o. Changes in Blood ejection and perfusion were significant when upper body elevations were increased to a higher angle. Results showed highest blood ejection and perfusion in normal supine posture or elevated supine posture (30° elevation only) for most of the subjects. Optimum blood ejection and perfusion are desirable for better performance in blood circulation as well as to meet body's metabolic needs. It is recommended highly to sleep in supine posture with no elevation or 30° elevated supine posture only if the subject prefers to sleep in some elevation.

  • Automatic Diagnosis of Cardiac Diseases by Cepstral Processing of Bioimpedance Signal

    The bioimpedance method used in this study consists of application of rectangular electrical current (30 Khz, 1 mA), which is harmless to the patient, by means of two electrodes placed respectively in the front and above the leading edge of the heart. Two electrodes, placed on the chest of the patient at the level of aorta 2 or 3 cm apart, permit perception of bioimpedance signal (BS) representing impedance variation DeltaZ of the explored thoracic region.

  • Body composition analysis using various anthropometric equations

    Bioimpedance analysis is the method used which provides information related to the correct health status. Various body composition methods are available used to measure body composition. Body composition measurement is done either by single frequency, multifrequency. In order to measure impedance of human body current is injected into tissues. With the help of AFE4300 impedance spectrometer it is possible to perform both single and multifrequency measurement. AFE4300 is the impedance spectrometer developed by Texas Instrument able to measure various body composition parameters like FFM, FM, TBW, ICW, ECW and BMI etc. Single frequency measurement is done at 50 KHz; multifrequency measurement is done at five different frequencies using AFE4300EVM-PDK board like 8 KHz, 16 KHz, 32 KHz, 64 KHz and 128 KHz etc. Single frequency measurement is done using FWR and Multi-frequency measurement is done using I/Q demodulator. It contains two chains one is used for body composition measurement other for weight scale measurement only one chain is activated at same time, In this work we use AFE4300 EVM-PDK board for body composition measurement purpose. After measuring body composition parameters, body composition analysis done through various anthropometric equations.

  • Estimation of Body Composition in Dialysis Patients Using Segmental Bioimpedance

    Accurate estimation of body muscle, fat and fluid volumes in dialysis patients is an important factor to predict outcomes of the disease. Bioimpedance spectroscopy (BIS) has been used to measure extracellular (Re) and intracellular resistance (Ri) with whole body (wBIS) and segmental (sBIS) measurement. 40 stable HD patients (22 m / 18 f, age 54.7 plusmn11 yrs, height (H) 1.67 plusmn 0.94 m, weight (Wt) 77.7 plusmn 17 kg) were studied with wBIS and sBIS compared to the gold standard measurements by MRI and tracer dilution assays (D<sub>2</sub>O and NaBr) pre dialysis. Multiple linear regression models were constructed with body compartment estimates from the gold standard methods as the dependent variables and bioimpedance-derived resistances, Wt, H, and age as independent variables. The results of estimation for fat (r<sup>2</sup> = 0.96 and r<sup>2</sup> = 0.91), for muscle (r<sup>2</sup> = 0.9 and r<sup>2</sup> = 0.88) and for ECV (r<sup>2</sup> = 0.73 and r<sup>2</sup> = 0.59) were from sBIS and wBIS model respectively. In conclusion, the sBIS model is useful to assess body composition in dialysis patients.
