A syringe pump is disclosed that includes a body, a syringe seat, a syringe actuator, a memory, and one or more processors. The syringe seat is coupled to the body. The syringe actuator is configured to actuate a syringe secured within the syringe seat. The memory is configured to store a plurality of instructions. The one or more processors, in accordance with the plurality of instructions, is/are configured to: prime the syringe pump in a prime phase; determine if an occlusion exists during the prime phase using a first test; stop the prime phase; initiate fluid delivery into a patient; enter into a start-up phase; determine if an occlusion exists using a second test during the start-up phase; transition from the start-up phase into a steady-state phase; and determine if an occlusion exists during the steady-state phase using a third test.
