METHODS AND SYSTEMS FOR DETERMINING FLUID ADMINISTRATION
First Claim
1. A physiological monitoring system comprising:
- a light detecting sensor configured to;
detect at least one wavelength of light absorbed through tissue of a subject; and
generate at least one physiological signal based on the detected at least one wavelength of light; and
a processor coupled to the light detecting sensor configured to;
receive the at least one physiological signal;
determine a value indicative of fluid responsiveness of the subject based on the at least one physiological signal;
receive a value indicative of regional oxygen saturation in a region of the subject'"'"'s tissue; and
determine whether to administer fluid to the subject based on the value indicative of regional oxygen saturation and the value indicative of fluid responsiveness.

Abstract
Methods and systems are provided for determining fluid administration. The system may determine fluid administration based on the fluid responsiveness and regional oxygen saturation of a subject. The system may receive the fluid responsiveness and regional oxygen saturation from external sources or may determine one or both based on received physiological signals. In some embodiments, the system may determine whether to administer fluid based on the fluid responsiveness and regional oxygen saturation. In some embodiments, the system may determine the amount of fluid to administer based on the fluid responsiveness and regional oxygen saturation. In some embodiments, the system may determine the effectiveness of fluid administration. In some embodiments, the system may provide an indication of the determined fluid administration so that a care-giver can implement the appropriate fluid administration. In some embodiments, the system may control the fluid administration based on its determination.

12. A physiological monitoring system comprising:
-
an input configured to receive a plurality of physiological signals, wherein the plurality of physiological signals are indicative of light absorbed by the subject; a saturation calculator coupled to the input configured to calculate regional oxygen saturation in a region of the subject'"'"'s tissue based on at least two of the plurality of physiological signals; a fluid responsiveness calculator coupled to the input configured to calculate a parameter indicative of fluid responsiveness based on at least one of the plurality of physiological signals; and a fluid administration calculator configured to provide an indication regarding the administration of fluid to the subject based on the regional oxygen saturation and the parameter indicative of fluid responsiveness. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
