PROCESS AND MEASURING INSTRUMENT FOR DETERMINING THE RESPIRATION RATE
First Claim
1. A process for determining the respiration rate of a patient by means of vessel plethysmography, the process comprising the steps of:
- setting up a control and analysis unit to apply and send an alternating voltage through the body;
determining an electric impedance between at least two electrodes by means of the control and analysis unit connected to the body via a plurality of electrodes; and
automatically recording and analyzing the determined values for an indicator of the impedance as a function of the time in order to determine the respiration rate therefrom.

Abstract
A process for determining the respiration rate of a patient by means of vessel plethysmography. Provisions are made according to the present invention for determining the electric impedance between at least two electrodes by means of a control and analysis unit connected to the body via a plurality of electrodes, for which the control and analysis unit is set up to send an alternating voltage through the body and to determine an indicator of the impedance between at least two electrodes, and to automatically record and evaluate the determined value for the indicator of the impedance as a function of the time in order to determine the respiration rate therefrom.
