Centrifugal Pumps – An overview – Cardiovascular Perfusion

07/12/2016  Centrifugal pumps for CPB have been commercially available since 1976. At many institutions, the centrifugal pump has replaced roller pumps for routine CPB for cardiovascular surgery. They are also used for mechanical circulatory support, including ventricular assistance, percutaneous cardiopulmonary support, and extracorporeal membrane oxygenation. Characteristics The basic

Cardiopulmonary bypass machine - CPB - EBME Website

The CPB pump itself is often referred to as a heart-lung machine or "the pump". Cardiopulmonary bypass pumps are operated by perfusionists in association with surgeons who connect the pump to the patient's body. CPB is a form of extracorporeal circulation. Cardiopulmonary bypass is commonly used in heart surgery because of the difficulty of operating on the beating heart. Operations requiring ...

Adult cardiac surgery outcomes: role of the pump type ...

Centrifugal pumps have been widely used as the main pump in adult cardiac surgery, and are considered by some authors to be superior to the traditionally used roller pumps because of less blood trauma , reduced activation of the coagulation cascade and improved biocompatibility , even if some of the studies could not document any significant benefits in terms of hemolysis , platelet damage or immune

The Impact of Roller Pump vs. Centrifugal Pump on ...

Centrifugal pumps are considered to be less destructive to blood elements (1) when compared to roller pumps. However, their large prime volumes render them unsuitable as arterial pumps in heart lung machine (HLM) circuitry for children. In November of 2014, the circuit at Arnold Palmer Hospital, a Biomedicus BP-50 with kinetic assist venous drainage (KAVD) and 1/4″ tubing was converted to a

Postoperative support with the centrifugal pump ...

Centrifugal pump left ventricular assist device is a useful adjunct in pediatric cardiac surgery, as a bridge to recovery, or in some cases, to transplantation. This form of circulatory support may not have the universal applicability of extracorporeal membrane oxygenation, but it is equally or more effective in properly selected patients. The technology for centrifugal pump support is now quite standardized,

Centrifugal pump use can be helpful in reducing the occurrence of some of the most feared neurological complications of adult cardiac surgery patients. This study was performed to assess if the kind of pump used for CPB (roller vs. centrifugal) can influence neurological outcomes of adult cardiac surgery

Cardiopulmonary bypass machine - CPB - EBME Website

CPB is a form of extracorporeal circulation whose function is circulatory and respiratory support along with temperature management to facilitate surgery on the heart and great vessels. The CPB pump itself is often referred to as a heart-lung machine or "the pump". Cardiopulmonary bypass pumps are operated by perfusionists in association with surgeons who connect the pump to the patient's body. CPB is a form

Centrifugal Pump - an overview ScienceDirect Topics

Cardiac output from a centrifugal pump depends on preload, afterload, and the rotational speed of the pump. A flow probe is necessary because increases or decreases in preload and afterload can affect pump flow without changes in rotational speed. Excessive negative inlet pressures (hypovolemia) must be avoided because air can be entrained into the circuit. The main limitation of centrifugal ...

Roller Pump - an overview ScienceDirect Topics

In the setting of short-term CPB for cardiac surgery, it remains uncertain whether the selection of a roller pump over a centrifugal pump, or of any specific centrifugal pump over another, has clinical importance. Pulsatile perfusion may prove to be beneficial in the future, but further outcome data and technical improvements are needed. 9

This study was performed to assess if the kind of pump used for CPB (roller vs. centrifugal) can influence neurological outcomes of adult cardiac surgery patients. Between 1994 and 1998, 3438 patients underwent coronary and/or valve surgery at our hospital; of these, 1805 (52.5%) underwent surgery with the use of a centrifugal pump, and 1633 (47.5%) were operated with a roller pump.

Further reductions in pump size, centrifugal design, and intrapericardial positioning may reduce complications and improve outcomes. Methods and Results— We studied a small, intrapericardially positioned, continuous-flow centrifugal pump in patients requiring an implanted ventricular assist device as a bridge to heart transplantation. The course of investigational pump recipients was ...

Ventricular Assist Device NHLBI, NIH

13/05/2015  A surgeon will open your chest and connect your heart’s arteries and veins to a heart-lung bypass machine. Your surgeon will place the pump in the upper part of your belly wall and connect the pump to your heart with a tube. Another tube will connect the pump to one of your major arteries. The VAD will be connected to the control unit and power source outside your body. When the heart-lung

Technical Aspects of Cardiopulmonary Bypass

Centrifugal pumps then send blood to a heat exchanger and then a membrane oxygenator (less traumatic than bubble oxygenators which are highly efficient but which induce hemolysis and platelet destruction, and activate the complement system if bypass times exceed 90 minutes). Thermal control is critical, as each degree C lowers metabolic rate by 8% (at 28C, metabolic rate is 50% of baseline ...
