1. An intravenous (“

  • IV”

    ) liquid delivery system comprising;

    an IV pump tubing set;

    a pump actuator operable with the IV pump tubing set;

    an upstream valve actuator operable with the IV pump tubing set upstream of the pump actuator;

    a downstream valve actuator operable with the IV pump tubing set downstream of the pump actuator;

    an air purge valve actuator operable with the IV pump tubing set downstream of the downstream valve actuator; and

    an air removal device located between the downstream valve actuator and the air purge valve actuator;

    at least one air detector for detecting air in the IV pump tubing set; and

    the system configured, upon receipt of a signal indicating air from the at least one air detector, to (i) close the air purge valve actuator, and (ii) force air in the IV pump tubing set to be purged through the air removal device.
