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.
