Regarding ECF and also ICF evaluation making use of SF-BIA, a number of research performed ended up according to way of measuring involving bioimpedance within 60 KHz consistency, Sergi et ing. [94], foresee ECF utilizing two wavelengths (1 and 60 KHz): ECF50KHz=?5.22+0.20Ht2/R50+0.005Ht2/Xc50+0.08Wt+1.9Health+1.86Sex (Twenty one) ECF50KHz=?7.24+0.34Ht2/R1+0.06Wt+2.63Health+2.57SexSex{1,Male0,Female;Health{1,Healthy2,Diseased [https://en.wikipedia.org/wiki/Astemizole Astemizole] (22) After measurements performed using bioimpedance and bromide dilution methods on 40 subjects (19 males and 21 females) aged 21�C81 years, of which 22 were healthy subjects, 12 were affected by chronic heart failure and 6 by chronic renal failure, the best estimation results at 1 KHz achieved a correlation coefficient (R2) and standard estimation error equal to 0.89 and 1.7 L. Due to incomplete conduction of the intracellular fluid at 50 kHz [2], MF-BIA was proposed to increase accuracy of estimation of TBW, ECF and ICF. Deurenberg et al. [95] used MF-BIA (1, 5, 50, 100 KHz) to predict TBW using Z100KHz and Z50KHz; and ECF using Z1KHz and Z5KHz among 139 normal adult subjects with reference to deuterium [http://www.selleckchem.com/products/PLX-4720.html PLX-4720 concentration] oxide dilution and bromide dilution: TBW100KHz=6.69+0.34573Ht2/Z100+0.17065Wt?0.11Age+2.66Sex (23) TBW50KHz=6.53+0.36740Ht2/Z100+0.17531Wt?0.11Age+2.83Sexsex{1,Male0,Female (24) The prediction equation of TBW achieved a correlation coefficient (R2) and standard error of estimate (SEE) equal to 0.95 and 1.73 L using Z100KHz, and 0.95 and 1.74 L using Z50KHz: ECF1KHz=2.30+0.19528Ht2/Z1+0.06987Wt?0.02Age (25) ECF5KHz=2.53+0.18903Ht2/Z5+0.06753Wt?0.02Age (26) The prediction equation of ECF achieved a correlation coefficient (R2) and standard error of estimate (SEE) equal to 0.87 and 0.98 L using Z1KHz, and 0.86 and 1.02 L using Z5KHz. Prediction of body fluids using the BIS method in three steps involves firstly determination using the values of Re from R0 and Rinf, secondly, inclusion of the body shape factor Kb due to the variation of body segments, and thirdly, inclusion of apparent resistivity ��a instead of the general resistivity �� as stated by Hanai in mixture theory [18]: ��a=��(1?c)32 (27) where (c) is volume fraction [http://www.selleckchem.com/products/necrostatin-1.html learn more] of non-conducting tissue. Based on Hanai's mixture method [18], tissue resistance (R) is measured based on conductive tissue, so it should exclude non-conducting tissue. Thus, by substituting Equation (27) in Equation (11), the apparent resistance (Ra) can be calculated using the following Equation (28): Ra=Kb��Ht2Vb(1?c)3/2 (28) At low frequencies the current will pass through extracellular fluids only without intracellular fluid due to the high capacitance of cell membranes [96]. In that case the conducting volume is equal to the ratio between ECF volume (Vecf) and TBW volume (Vb).
