1. A blood flow control system comprising:
a blood flow control device for placement within a body of a patient, the blood flow control device comprising an expandable member, a proximal sensor proximal to the expandable member, and a distal sensor distal to the expandable member, wherein each of the proximal and distal sensors is configured to measure a physiologic condition of the patient; and
one or more controllers communicably coupled to each of the proximal and distal sensors and configured to:
receive data indicative of the physiologic condition of the patient from the proximal and distal sensors;
compare the received data with target data;
identify at least one error based on the comparison; and
in response to identifying the error, inhibit at least one function of the blood flow control system,
wherein the received data is proximal blood pressure from the proximal sensor and distal blood pressure from the distal sensor, and the one or more controllers is further configured to compare at least one of the proximal blood pressure and the distal blood pressure to a target value.
