Abstract
A method includes detecting a condition including one or more of a change in flow of a fluid and a change in a composition of the fluid, issuing an alarm in response to the condition detected, lowering a flow rate; and attempting to restart process and increase the flow rate. The change in flow may include a change in pressure. The change in flow may be associated with a collapsed vein. The change in flow of the fluid may include detecting that the flow rate has fallen below a threshold. The change in the composition may be associated with a color. The change in the composition may include using a color sensor to detect one or more of a red, a green, and a blue reflection or transmission to detect red blood cells.
