Considering the model results for LTM and ATM in controls, it is important to note that the equivalence of OH across different paths does not translate to these compartments.

Body Composition Monitor

Journal of fresenis physiology Bethesda, Md. This characterises the individual differences freseniys fluid status and body composition and accounts for this when describing the differences between the paths at the cohort level. Estimation of RI has much greater uncertainty and for segmental measurements, especially, in the trunk, the data were largely uninformative. The paths included in the model were limited to the 6 whole-body paths: Significance levels were set at 0.

Changing from a whole-body measurement to a hand-to-hand or cross measurement will involve substitution of one limb for another and a change in the pathway through the trunk.

This is based on a number of key observations:. Details of model checking can be seen in Appendix 2.

Routine target weights were defined on the basis of clinical examination and BCM on indication. Journal of renal care. At a population level, it is becoming well accepted that using BCM as an aide in guiding fluid management fresneius haemodialysis improves outcomes Onofriescu et al.

Bland Altman analysis of the agreement of change in weight and change in OH. Where accurate monitoring of body composition is important, the standard pathway is preferred and consistency is important. Current opinion in clinical nutrition and metabolic care. Practicalities and staffing levels can sometimes make it difficult to carry out all necessary BCM measurements at the same time as putting patients on dialysis, while post-dialysis measurements gresenius allow immediate fresnius to be taken when intradialytic symptoms prompt a review of target weights.

Open in a separate window. The effect of utilising alternative measurement paths was assessed using mixed effects models and the effect of measuring post-dialysis was assessed by comparing changes in BCM-measured overhydration OH with weight changes over dialysis.

The views expressed in this publication are those of the authors and not fresenis those of the NHS, the National Institute for Health Research or the Department of Health.

Fresenius Medical Care; Sum of segmental bioimpedance analysis during ultrafiltration and hemodialysis reduces sensitivity to changes in body position.

Body composition monitor (BCM)

When considering fresennius measurements, it is accepted that haemodialysis induced changes in fluid distributions affect whole-body bioimpedance Zhu et al. Sample size Pilot work comparing BCM measurements from hand-to-hand and from hand-to-foot showed standard deviations of the mean difference in OH of around 1. Probing the dry weight by bioimpedance: This is based on a number of key observations: Changes in hydration following haemodialysis estimated with bioimpedance spectroscopy.

However, dialysis has been shown to perturb fluid distributions Shulman et al.

Statistical analysis To investigate the validity of fresemius measurements, the agreement between change in BCM-measured OH from the reference path and change in weight was assessed using Bland-Altman analysis. Assessment of fat-free mass using bioelectrical impedance measurements gresenius the human body.

The haemodialysis population is highly comorbid and is disproportionately prone to amputations and tissue viability problems. The 8-lead device does not display Cole-plots or body composition data to allow real-time assessment of artefacts or consistency, so repeat measurements were not made. Study limitations The study was freseniuus powered to address the multiple comparisons made by the models – the sample size was based on comparisons between the two primary whole-body paths only.

The potential for the equivalence of impedance across different paths was demonstrated two decades ago using bioimpedance analysis BIA measurements Lukaski et al. Yet there is a lack of data to support use of BCM outside this standardised approach and there remains a great deal of uncertainty in utilisation of the technology in certain individuals.

Methods Subjects Ethical approval was granted by a local ethics committee and all participants provided informed consent.

Specifications of an 8-lead BCM measurement. Frsenius and 8-lead BCM measurements were made on healthy subjects on one occasion while dialysis patients had measurements made pre- and post-dialysis.

Furthermore, the consistency of LTM and ATM from the start to end of dialysis was assessed based on the effect of measurement time in each of the mixed-effects models. Dialysis patients showed similar results other than having higher BCM-measured OH when measured across the site of a vascular access. Effect of change in fluid distribution in segments in hemodialysis patients at different ultrafiltration rates on accuracy of whole body bioimpedance measurement.

For each of the 17 paths, the measured fresenjus was fitted to the Cole equation as described by De Lorenzo et al. Bland Altman analysis was done using Analyse-it for Microsoft Ffesenius version 2.

For these models, measurement time was included as a predictor variable to investigate the validity of post-dialysis measurements of LTM and ATM. Rapid plasma volume decline upon quiet standing reflects large filtration capacity in dependent limbs.

De Lorenzo et al. Conclusions In summary, these data helps BCM users make measurements and interpret freenius with greater confidence. Pilot work comparing BCM measurements from hand-to-hand and from hand-to-foot showed standard deviations of the mean difference in OH of around 1.

Segmental bioelectrical impedance analysis. The evidence supporting this recommendation comes freseniux studies using different bioimpedance with different analysis techniques to the BIS used in the BCM. Bioelectrical impedance analysis–part I:
