Real-time monitoring of the state of the autonomous nervous system of a patient
First Claim
1. A method for monitoring the state of the autonomous nervous system of a patient, the method comprising the steps of:
- acquiring a first measurement signal from a patient, the first measurement signal representing a physiological signal measured from the patient;
obtaining a second measurement signal indicative of a respiration rhythm of the patient; and
generating, based on the first and second measurement signals, at least one indicator signal for obtaining an indication of the state of the autonomous nervous system of the patient.

Abstract
The invention relates to a method and arrangement for monitoring the state of the autonomous nervous system (ANS) of a patient. A first measurement signal is acquired from a patient, the first measurement signal representing a physiological signal measured from the patient. In order to enable real-time monitoring of the state of the ANS, a second measurement signal indicative of a respiration rhythm of the patient is acquired and at least one indicator signal is generated by means of the first and second measurement signals. The at least one indicator signal may then be used to obtain an indication of the state of the autonomous nervous system of the patient.
