What describes a properly set roller pump?

A properly set roller pump should be just occlusive. This means that the roller pump should compress the tubing enough to create an effective seal, allowing for the movement of fluid while preventing backflow. The idea is to promote consistent and pulsatile flow, which is crucial for maintaining the correct flow rates during procedures.

If the pump is overly compressive or completely occlusive, it could impede the flow, leading to potential damage to the tubing and possible clotting of blood or other fluids within the circuit. Conversely, if there is no occlusion, the fluid will not be moved effectively through the system, resulting in inadequate or no perfusion.

Thus, the optimal setting is one that is just occlusive, achieving a balance between effective fluid transport and the integrity of the pump and tubing system.
