Methods and systems for analyzing the state of an autonomic dysfunction of an autonomic nervous system for caring for a patient are disclosed. In some embodiments, the method includes measuring an autonomic nervous system condition, and calculating a root of a sum of values. One or more of the values is equal to a sum of difference values raised to an exponent, and the difference values are each equal to a difference of a first index value and a second index value. The first and second index values are each calculated based on the autonomic nervous system condition. The method also includes displaying, via a display unit, a representation of the calculated root.
