The pump console commonly incorporates several rotating motor-pushed pumps that peristaltically “rub down” tubing. This motion gently propels the blood via the tubing. This is normally known as a curler pump, or peristaltic pump. The pumps are greater low cost than their centrifugal counterparts, but are prone to overpressurization if the lines become clamped or kinked. They also are much more likely to reason a big air embolism and require constant, near supervision through the perfusionist.
