TOTAL BODY WATER IN ELDERLY PATIENTS

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 本研究的目的是设计一个简单的方法来测量身体水室在老年人的基础上，总身体水（TBW）使用生物电阻抗分析（BIA）。这种相对较新的方法是一种无创和简单的床边技术，可用于预测TBW，细胞外水（ECW），并确定危重病后改变的液体分布。此外，我们还想进行一项“金标准”研究（尿液渗透压），以验证BIA测量身体成分的方法。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The purpose of this study is to design a simple method of measuring body water compartments in elderly subjects based on total body water (TBW) using bioelectrical impedance analysis (BIA). This relatively new method is a noninvasive and simple bedside technique that can be used to predict TBW, extracellular water (ECW), and identify altered fluid distribution following critical illness. In addition, we would also like to perform a "gold standard" study (Urine Osmolality) to validate the BIA method of measuring body composition.
