Jenny E. Freeman, +3 more
TLDR
In this article, a bioimpedance measurement system is described, where a stabilized high frequency current generator is connected to PadSet electrodes via a Patient Cable, and electrodes are connected to an adaptive circuit that conditions the resulting voltage signal and converts it to digital form.
Abstract: 
Disclosed is a bioimpedance measurement system: A stabilized high frequency current generator is connected to PadSet electrodes via a Patient Cable. Electrodes are connected to an adaptive circuit that conditions the resulting voltage signal and converts it to digital form. Firmware performs signal acquisition and relays data to the device.
