Abstract: A system and method for determining FRC, TGV, TLC, and RV includes a hand-held unit with a shutter assembly designed to minimize measure air displacement due to shuttering. Measurement of flow and pressure are used to derive the lung parameters.

Abstract: The present invention relates to a device, system and a method for determining lung volume and parameters, and in particular, to such a spirometer device, system and method in which a non-occluding shutter is utilized allowing for continuous airflow through the flow tube.

Abstract: Provided are methods for determining the health status of subject considered as a potential intestinal microflora donor, and to compositions including bacteria obtained from healthy subjects. Further provided are methods of identifying individuals of exceptional health suitable to be donors of bacteria of the intestinal microflora, and methods for producing reproducibly effective probiotic compositions, and probiotic compositions derived from such bacteria.

Abstract: A method for measuring the air capacity of a user's lungs. The method involves the use of an apparatus which includes a container having a constant volume and an opening adapted to allow flow communication with the lungs. The container further includes a flow sensor and a pressure sensor. The method involves determining the initial air pressure in the container before flow communication with the lungs is established. After flow communication with the lungs is established, the flows and pressures are measured. The lung air capacity is calculated based on the known constant container volume, the initial air pressure, and the changes in volume and pressure of the lungs as determined from the measured flows and pressures in the container.
