1. A method for measuring a change in lung volume, comprising:
- placing a first pair of electrodes in contact with opposite arms of a human body;
placing a second pair of electrodes in skin contact with the midaxillary line on opposite sides of the human body;
measuring a parameter for impedance pneumography by tetrapolar impedance measurement, comprises;
feeding a current to the first pair of electrodes in contact with the opposite arms of the human body and measuring a voltage by the second pair of electrodes in skin contact with the midaxillary line on opposite sides of the human body, orfeeding a current to the second pair of electrodes in skin contact with the midaxillary line on opposite sides of the human body and measuring a voltage by the first pair of electrodes in contact with the opposite arms of the human body.
