Endovascular perfusion augmentation for critical care

A method for regulating blood flow comprising:

• inserting a catheter into an aorta of a patient, the catheter comprising a proximal end, a distal end, an expandable device at the distal end, a first sensor proximal to the expandable device, and a second sensor distal to the expandable device;
• measuring one or more physiological parameters of the patient using the first and second sensors;
• determining an amount of occlusion in the aorta provided by the expandable device based on the one or more measured physiological parameters;
• and
• determining a working range of the expandable device based on the amount of occlusion, the working range comprising an upper set point and a lower set point.

A blood flow regulation system comprising:

• a catheter having a distal end and a proximal end;
• an expandable device at the distal end of the catheter, the expandable device configured for placement within an aorta of a patient;
• a first sensor disposed on the catheter proximal to the expandable device, and a second sensor disposed on the catheter distal to the expandable device, wherein the first and second sensors are configured to measure one or more physiological parameters of the patient;
• and
• a processor operatively coupled to the first and second sensors, the processor configured to determine a working range of the expandable device, the working range comprising a lower set point and an upper set point, each of the lower and upper set points based on the one or more measured physiological parameters.
