SYSTEMS AND METHODS FOR MONITORING CLINICAL PROCEDURES USING REGIONAL BLOOD OXYGEN SATURATION
First Claim
1. A physiological monitoring system comprising:
- light drive circuitry configured for generating a light drive signal configured to cause one or more light sources to emit a plurality of light signals, wherein the plurality of light signals corresponds to a plurality of wavelengths of light;
one or more signal inputs configured for;
receiving a first plurality of light signals that have been attenuated by a first region of a subject, wherein the first plurality of light signals corresponds to the plurality of wavelengths of light;
receiving a second plurality of light signals that have been attenuated by a second region of the subject, wherein the second plurality of light signals corresponds to the plurality of wavelengths of light; and
receiving clinical information associated with the subject undergoing an infusion pump procedure for sodium nitroprusside administration; and
one or more processors configured for;
monitoring regional blood oxygen saturation (rSO2) of the subject based on the first received plurality of light signals and the second received plurality of light signals;
detecting a change in the rSO2 of the subject;
determining status information for the subject based on the clinical information and the detected change in the rSO2 of the subject; and
triggering an action based on the status information.

Abstract
Methods and systems are presented for monitoring a clinical procedure using regional blood oxygen saturation (rSO2) of a subject. The rSO2 of a subject is monitored, and clinical information is received, indicating that the subject is undergoing a clinical procedure (e.g., an infusion pump procedure for sodium nitroprusside administration). A change in the rSO2 of the subject is detected, which may be indicative of a circulatory system impairment (e.g., elevated venous oxygen saturation) caused by the clinical procedure. Status information, which may be indicative of an increased risk of a physiological event (e.g., cyanide toxicity) is determined for the subject based on the clinical information and the detected change in the rSO2 of the subject. Corrective actions may be triggered based on the status information in order to reduce the increased risk. The corrective actions may be implemented as smart prompt or closed loop systems.

17. A physiological monitoring system comprising:
-
a signal input configured for receiving clinical information associated with a subject undergoing a clinical procedure, wherein the clinical procedure affects the circulatory system of the subject; and one or more processors configured for; monitoring regional blood oxygen saturation (rSO2) in a region of the subject that is affected by the clinical procedure; detecting one or more changes in the rSO2 in the region of the subject; determining status information associated with the subject based on the one or more changes in the rSO2 in the region of the subject and the clinical information; and triggering an action based on the status information. - View Dependent Claims (18, 19, 20)
