Abstract
An electrode padset and a method of using the electrode padset are disclosed herein. The electrode padset is a single unit, consisting of multiple patient-contacting conductive pads arranged on a single piece of material. The padset is comprised of a plurality of conductive pads, at least one conductive pad adapted to emit an electrical signal and at least one other conductive pad adapted to receive an electrical signal, and an electrically conductive material coupling the conductive pads.
Claims41
A system for measuring bioimpedance signals, comprising:
- an electrode padset, wherein the electrode padset comprises:
- a pair of sternal electrodes;
- a pair of side electrodes;
- a xiphoid electrode;
- and
- an electrically conductive material coupling the pair of sternal electrodes and the pair of side electrodes to the xiphoid electrode;
- a microprocessor adapted to be in communication with and receive bioimpedance signals from the electrode padset and measure the bioimpedance of a patient;
- and
- a parasitic impedance mitigation system.
A method of obtaining a bioimpedance signal, comprising:
- selecting a padset for use on a patient;
- coupling the padset to a microprocessor;
- selecting software based on the selected padset, wherein the software is adapted to remove parasitic impedance of the padset based on the padset's geometry;
- delivering a current to the patient via the padset;
- receiving the current from the patient via the padset;
- filtering out the parasitic impedance;
- determining the impedance of the patient;
- calculating at least one respiratory volume measurement of the patient;
- and
- outputting the calculating at least one respiratory volume measurement of the patient.
