Method and apparatus for bioimpedance

Numerous methods and devices are known which can be done a mobile vital signs collection. Usually make such devices while some sensed parameters available, but are not able to infer a body condition in detail. This should eliminate the invention. For this purpose, the derived parameters are combined to form a total image, which is then evaluated by means of a microcontroller and compared with comparable stored state values. From this it is then a body condition, such as sleep, but especially symptoms such as sleep apnea, is determined. The required accuracy of the measurement is made by exclusion of artifacts by several different sources will be used for evaluation.
