1. A method of performing remote ischemic preconditioning, the method comprising:
- positioning a cuff about a limb of a subject;
initiating a treatment protocol that includes a plurality of treatment cycles that include at least a first treatment cycle and a second treatment cycle,the first treatment cycle comprising;
compressing the limb of the subject with the cuff to a pressure above systolic pressure to occlude blood flow through the limb for a first ischemic duration that last for at least a minute; and
releasing pressure applied to the limb by the cuff to allow blood flow through the limb for a first reperfusion duration that lasts at least one minute;
the second treatment cycle comprising;
compressing the limb of the subject with the cuff to a pressure above systolic pressure to occlude blood flow through the limb for a second ischemic duration that last for at least a minute; and
releasing pressure applied to the limb by the cuff to allow blood flow through the limb for a second reperfusion duration that lasts at least one minute;
removing the cuff from the limb of the subject;
wherein the first ischemic duration and the second ischemic duration are of different lengths of time.

Abstract
A system for remote ischemic preconditioning that includes a cuff, and actuator, and a controller that operates the actuator according to a treatment protocol. The treatment protocol includes a plurality of treatment cycles that each comprise cuff actuation, an ischemic duration, cuff release, and a reperfusion duration.

9. A method of performing remote ischemic preconditioning, the method comprising:
-
positioning a cuff about a limb of a subject; initiating a treatment protocol that includes a plurality of sequentially actuated treatment cycles, including a first treatment cycle, a second treatment cycle, and a third treatment cycle; the first treatment cycle comprising; compressing the limb of the subject with the cuff to a pressure above systolic pressure to occlude blood flow through the limb for a first ischemic duration that last for at least a minute; and releasing pressure applied to the limb by the cuff in to allow blood flow through the limb for a first reperfusion duration that lasts at least one minute; the second treatment cycle comprising; compressing the limb of the subject with the cuff to a pressure above systolic pressure to occlude blood flow through the limb for a second ischemic duration that last for at least a minute; and releasing pressure applied to the limb by the cuff to allow blood flow through the limb for a second reperfusion duration that lasts at least one minute; the third treatment cycle comprising; compressing the limb of the subject with the cuff to a pressure above systolic pressure to occlude blood flow through the limb for a third ischemic duration that last for at least a minute; and releasing pressure applied to the limb by the cuff in to allow blood flow through the limb; removing the cuff from the limb of the subject; wherein the first reperfusion duration and the second reperfusion duration are of different lengths of time. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A system for remote ischemic preconditioning, the system comprising:
-
a cuff configured to retract about a limb of a subject; an actuator connected to the cuff and that, when actuated, causes the cuff to contract about the limb of the subject to reduce blood flow therethrough; and a controller that controls the actuator to operate according to a treatment protocol that includes a plurality of sequentially actuated treatment cycles, each treatment cycle comprising; cuff actuation, during which the actuator contracts the cuff about the limb of the subject to a pressure above systolic pressure to occlude blood flow through the limb; an ischemic duration, during which the cuff is contracted about the limb above systolic pressure to occlude blood flow through the limb, the ischemic duration lasting for at least about a minute; cuff release, during which the actuator releases the cuff to allow blood flow through the limb; and a reperfusion duration, during which the cuff is in an at least partially relaxed state to allow blood flow through the limb, the reperfusion duration lasting for at least one minute. - View Dependent Claims (20, 21, 22)
