Abstract
The present invention relates to a procedure for measuring a patient's impedance. Based on the impedance, it is possible to monitor the patient's respiration and/or blood circulation. In the procedure, a plurality of electrodes (1a, 1b; 1d, 2; 2a) are connected to be patient and the changes in the impedance relationships between the electrodes (1a, 1b, 2) are measured. The invention makes it possible to use the same measuring conductors and measuring electrodes for impedance measurement as are used in ECG measurement.
