摘要：
Devices, systems, and techniques for transitioning between different drug delivery sources or different drug concentrations may account for diffusion and mixing of drug within the fluid. In one example, a method may include determining a flow rate for a fluid to be delivered to a patient via a drug pump and a catheter in fluid communication with a reservoir of the drug pump. The fluid includes a drug. The method also includes determining a concentration profile of the drug delivered via the catheter, wherein the concentration profile identifies a volume of delivered fluid needed to achieve a target transition dose of the drug. The method further includes determining, by a processor and based on the flow rate and the concentration profile, an initial delivery period required to achieve the target transition dose by delivering the fluid at the flow rate.
