项目摘要

The purpose of the proposed research is to establish the feasibility of a novel plethysmographic approach to the determination of human body volume and composition. The need for a practical, accurate, non-invasive and low cost device for the measurement of body composition is well established for the general population, where excess body fat is associated with many disease processes, e.g., cardiovascular disease, diabetes, and pulmonary disease. Also important is the assessment of body composition and nutritional status of normal and low birth weight infants, for whom caloric reserves are critical. A whole body plethysmograph is used to determine body volume and subsequent body density. The volume of air in the chamber is perturbed by a small loudspeaker, and the spectral energy of the resulting pressure change is analyzed. The procedure is entirely comfortable and minimal patient compliance is required. Based on demonstration of technical feasibility, the proposed research will lead to development of a new method of body composition determination that will be highly attractive for commercial application. Commercial application will be found in the general population where the trend towards modification of controllable risk factors is now well established. Medical applications would include health care of low birth weight infants, patients with eating disorders, and the obese.

拟议研究的目的是确定一项测定人体体积的一种新的体积描记方法和构图。需要一种实用、准确、无创和低成本的为身体成分的测量建立了成本装置在普通人群中，过量的体脂与许多疾病过程，例如心血管疾病、糖尿病和肺病疾病。同样重要的是身体成分的评估和正常和低出生体重儿的营养状况储备是至关重要的。使用全身体积描记器来确定身体体积和随后的体密度。房间里的空气量被一个小的扬声器，由此产生的压力变化的频谱能量为分析过了。手术完全舒适，患者极少。合规是必需的。在论证技术可行性的基础上，拟议的研究将导致了一种新的身体成分测定方法的发展将对商业应用具有极大的吸引力。商业广告在普通人群中会发现应用程序的趋势是对可控风险因素的修正现在已经确立。医疗应用将包括对低出生体重儿的医疗保健，饮食失调的病人和肥胖者。
