Apparatus and methods for plethysmographic measurement of infant body composition

This invention relates generally to plethysmographic measurement of human body composition. More specifically, the present inventions relate to apparatus and methods for plethysmographic measurement of body composition for infant subjects. Apparatus and methods relating to plethysmographic measurement of infant body composition are provided. A tray for receiving the infant subject to be measured is coupled to a sliding mechanism that slides the tray in and out of a plethysmographic measurement chamber, thereby reducing the footprint of said chamber and facilitating infant comfort during measurement. Further, an integrated weighing function is provided that determines the infant's weight while conducting body composition measurements.
