US 2025/0049388 A1 · Adaptive Closed Loop Hemorrhagic Shock Resuscitation Controller

Abstract

Methods, devices, systems, and computer-readable media are described for providing adaptive and closed loop hemorrhagic shock resuscitation. A computing device may cause activation of an automated tourniquet configured to impede extremity bleeding. The computing device may additionally cause activation of an adaptive resuscitation controller by determining a desired mean arterial pressure setpoint and causing, based on the desired mean arterial pressure setpoint, the adaptive resuscitation controller to infuse fluids into the patient. The computing device may then monitor component pressure measurements of the automated tourniquet and blood pressure parameters of the patient. The computing device may then, based on the component pressure measurements, cause modification of one or more operating parameters of the automated tourniquet. The computing device may additionally and/or alternatively, based on comparing the blood pressure parameters to the desired mean arterial pressure setpoint, cause the adaptive resuscitation controller to infuse fluids into the patient.
