The method also includes transmitting a signal prior to initiation of a change in fluid delivery to the patient along a second fluid flow path connected to the first fluid flow path upstream of the patient, and detecting the signal. The method further includes actuating an alarm to alert the user to a potential unintended bolus delivery if the signal is detected. A system for carrying out the method is also provided. ## Claims ### Claim 1 A system for alerting a user to a potential unintended bolus delivery, the system comprising: a first fluid delivery system comprising a first fluid flow path, the first fluid delivery system configured to be in fluid communication with a patient along the first fluid flow path, the first fluid delivery system having a receiver; a second fluid delivery system comprising a second fluid flow path, the second fluid delivery system configured to be in fluid communication with the patient along the second fluid flow path, the second fluid flow path connected to the first fluid flow path between the first fluid delivery system and the patient, the second fluid delivery system having a transmitter in communication with the receiver and configured to provide a signal that travels along the second fluid flow path prior to initiation of the second fluid delivery system to change fluid delivery to the patient from the second fluid delivery system; the receiver configured to detect the signal as it travels along the first fluid flow path; and a controller coupled to the receiver, the controller programmed to determine if the signal has been received by the receiver and to alert the user to a potential unintended bolus delivery if the signal has been received by the receiver. ### Claim 2 (depends on 1) The system according to claim 1, wherein: the receiver is in communication with the first fluid flow path; and the transmitter is in communication with the second fluid flow path. ### Claim 3 (depends on 1) The system according to claim 1, wherein the controller is programmed to interrupt initiation of the second fluid delivery system prior to the change in fluid delivery to the patient from the second fluid delivery system. ### Claim 4 (depends on 3) The system according to claim 3, wherein the controller is programmed to permit the user to override the interruption of the initiation of the second fluid delivery system. ### Claim 5 (depends on 4) The system according to claim 4, wherein the controller is coupled via a communication link to the receiver. ### Claim 6 (depends on 5) The system according to claim 5, wherein the first fluid delivery system comprises an RF transmitter and the second fluid delivery system comprises an RF receiver, the communication link comprises the RF transmitter and the RF receiver, and the second fluid delivery system comprises the controller. ### Claim 7 (depends on 6) The system according to claim 6, where the controller receives information on the communication link regarding a medication delivered with the fluid to the patient by the first fluid delivery system. ### Claim 8 (depends on 1) The system according to claim 1, wherein the second fluid delivery system comprises an alarm actuated to alert the user to a potential unintended bolus delivery. ### Claim 9 (depends on 1) The system according to claim 1, wherein the first fluid delivery system is configured to deliver fluid to the patient at a first fluid flow rate and the second fluid delivery system is configured to deliver fluid to the patient at a second fluid flow rate that increases a combined delivery rate. ### Claim 10 (depends on 9) The system according to claim 9, wherein the second fluid flow rate is a multiple of the first fluid flow rate. ### Claim 11 (depends on 10) The system according to claim 10, wherein the second fluid flow rate is at least an order of magnitude greater than the first fluid flow rate. ### Claim 12 (depends on 1) The system according to claim 1, wherein the first fluid delivery system is configured to deliver a first medication to the patient, and the second fluid delivery system is configured to deliver a second medication to the patient. ### Claim 13 (depends on 1) The system according to claim 1, wherein the first fluid delivery system comprises a first pump and a first fluid container, and the second fluid delivery system comprises a second pump and a second fluid container. ### Claim 14 (depends on 13) The system according to claim 13, wherein the first and second containers comprise flexible-walled bags. ### Claim 15 (depends on 14) The system according to claim 14, wherein the first and second pumps each comprise a peristaltic pump. ### Claim 16 (depends on 15) The system according to claim 15, wherein: the first fluid flow path comprises at least one set connected at a first end of the first fluid flow path to the first fluid container and configured to be connected at a second end of the first fluid flow path to the patient, the at least one set comprising a connector disposed between the first and second ends, and the second fluid flow path comprises at least one set connected at a first end of the second fluid flow path to the second fluid container and at a second end of the second fluid flow path to the connector. ### Claim 17 (depends on 16) The system according to claim 16, wherein the connector comprises a Y-site connection. ### Claim 18 (depends on 1) The system according to claim 1, wherein the controller is coupled to an alarm, the controller programmed to actuate the alarm if the signal has been received by the receiver. ### Claim 19 (depends on 18) The system according to claim 18, wherein the alarm comprises an audible alarm or a visual alarm. ### Claim 20 (depends on 1) The system according to claim 1, wherein the transmitter is an acoustical transmitter and the receiver is an acoustical receiver. ### Claim 21 (depends on 1) The system according to claim 1, wherein the transmitter is an RF transmitter and the receiver is an RF receiver. ### Claim 22 (depends on 1) The system according to claim 1, wherein the transmitter is defined by a first transceiver, and the receiver is defined by a second transceiver.
