Abstract

The technology relates to a remote ischemic preconditioning system having a cuff configured to contract about a limb of a subject; an actuator connected to the cuff that, when actuated, causes the cuff to contract about the limb of the subject; a controller that controls the actuator to operate according to a treatment protocol that includes a plurality of treatment cycles of contracting and releasing the cuff about the limb of a subject; a first sensor for measuring oxygen saturation level in the blood of the limb; a second sensor for measuring a pulse property in the limb; and a feedback control unit in communication with the controller and configured to receive the oxygen saturation measurement from the first sensor and the pulse property from the second sensor; wherein the feedback control unit is further configured to: compare the oxygen saturation level to a first predetermined value and signal the controller to operate the actuator to further inflate the cuff if the oxygen saturation level is above the predetermined value; and compare the pulse property to a second predetermined value and signal the controller to operate the actuator to further inflate the cuff if the pulse rate or pulse strength is above the predetermined value.
