The donation process may include a plasma donation using an apheresis machine. The detecting the beginning of the donation process may include detecting a flow of fluid. The output may include one or more of a light and a sound. The output may be provided on a side of an apheresis machine. ## Claims ### Claim 1 A method comprising: detecting a beginning of a donation process; in response to detecting the beginning of the donation process, providing an output; determining an amount of time remaining for the donation process; in response to detecting the amount of time remaining for the donation process, updating the output; detecting a loss in pressure; in response to detecting the loss in pressure, updating the output; detecting an ending of the donation process; and in response to detecting the ending of the donation process, updating the output, wherein the output includes a display device displaying a series of lights and one or more of the lights of the series of lights are configured to pulse to instruct a donor to squeeze. ### Claim 2 (depends on 1) The method of claim 1, wherein the donation process includes a plasma donation using an apheresis machine. ### Claim 3 (depends on 1) The method of claim 1, wherein detecting the beginning of the donation process comprises detecting a flow of fluid. ### Claim 4 (depends on 1) The method of claim 1, wherein the output further includes a sound. ### Claim 5 (depends on 1) The method of claim 1, wherein the output is provided on a side of an apheresis machine. ### Claim 6 (depends on 1) The method of claim 1, wherein the output is within a range of the donor such that the output may be viewed and heard by the donor. ### Claim 7 (depends on 1) The method of claim 1, wherein the series of lights updates to illustrate to the donor a percentage of the donation process remaining. ### Claim 8 (depends on 7) The method of claim 7, wherein the percentage of the donation process remaining comprises an amount of time remaining in the donation process. ### Claim 9 (depends on 1) The method of claim 1, wherein the one or more of the lights of the series of lights are configured to pulse at a tempo associated with a rate at which the donor should squeeze to maintain pressure. ### Claim 10 (depends on 1) The method of claim 1, wherein detecting the loss in pressure comprises detecting that a pressure of a fluid in an apheresis machine drops below a predetermined threshold. ### Claim 11 (depends on 1) The method of claim 1, wherein in response to detecting the loss in pressure, updating the output comprises instructing the donor to squeeze. ### Claim 12 (depends on 1) The method of claim 1, wherein in response to detecting the ending of the donation process, the updating the output comprises one or more of ceasing an audible noise, turning off a light of the series of lights, changing a color of the light, and changing an audible sound.
