Efficiency The efficiency of centrifugal pumps varies over the individual curve. The most efficient point of two curves is illustrated in Figure 1. When sizing, it is helpful to select a pump whose curve puts the duty point as close to this bend in the curve as possible. Impeller Size Within a given housing, the impeller diameter will determine

A centrifugal pump is a mechanical device used to transport fluids by converting rotational energy from a motor or engine into kinetic energy in the fluid. It is one of the most common types of pumps used in various industries .
Cardiopulmonary bypass (CPB) is a crucial technique used during cardiac surgeries to temporarily take over the function of the heart and lungs. This allows the surgeon to operate on a still and bloodless field. One of the key components of a CPB circuit is the centrifugal pump, which plays a vital role in maintaining and controlling blood flow during the procedure.
Many CPB circuits now employ a centrifugal pump for the maintenance and control of blood flow during CPB. By altering the speed of revolution (RPM) of the pump head, blood flow is produced by centrifugal force. See more
Cardiopulmonary Bypass Explained
Cardiopulmonary bypass is a technique used to divert blood away from the heart and lungs, allowing for surgical procedures to be performed on these organs. The process involves connecting the patient to a heart-lung machine, which takes over the functions of the heart and lungs, oxygenating the blood and pumping it back into the body.
Cardiopulmonary Bypass Procedure Steps
The cardiopulmonary bypass procedure involves several key steps. Firstly, the patient is connected to the heart-lung machine through cannulas inserted into the major blood vessels. The blood is then diverted away from the heart and lungs, passing through the machine where it is oxygenated and pumped back into the body. The surgeon can then proceed with the necessary cardiac procedures while the heart is still and bloodless.
Cardiopulmonary Bypass Machine Diagram
A cardiopulmonary bypass machine typically consists of a pump, an oxygenator, tubing, and a heat exchanger. The pump, often a centrifugal pump, is responsible for maintaining blood flow during the procedure. The oxygenator oxygenates the blood, while the heat exchanger regulates the temperature of the blood before it is returned to the body.
Cardiopulmonary Bypass Circuit Diagram
The cardiopulmonary bypass circuit is a closed-loop system that circulates the patient's blood through the heart-lung machine. The circuit includes tubing, cannulas, a reservoir, a pump, an oxygenator, and a heat exchanger. The centrifugal pump within the circuit plays a crucial role in controlling blood flow by altering the speed of revolution (RPM) of the pump head.
What is a Cardiopulmonary Bypass?
Cardiopulmonary bypass is a technique that allows for the temporary support of the heart and lungs during cardiac surgeries. It involves diverting the patient's blood away from the heart and lungs, oxygenating it, and then returning it to the body. This process enables the surgeon to operate on a bloodless field, reducing the risk of bleeding during the procedure.
Indications for Cardiopulmonary Bypass
Cardiopulmonary bypass is indicated in various cardiac surgeries where the heart needs to be stopped to perform intricate procedures. Some common indications for CPB include coronary artery bypass grafting, valve replacement, and congenital heart defect repairs. The use of a centrifugal pump in the CPB circuit helps maintain stable blood flow throughout these procedures.
Cardiopulmonary Bypass Machine Cost
The cost of a cardiopulmonary bypass machine can vary depending on the manufacturer, model, and features included. A basic CPB machine with a centrifugal pump can range from tens of thousands to hundreds of thousands of dollars. The investment in a reliable and efficient CPB machine is essential for ensuring the safety and success of cardiac surgeries.
Cardiopulmonary bypass (CPB) or heart-lung machine, also called the pump or CPB pump, is a machine that temporarily takes over the function of the heart and lungs during open-heart surgery by maintaining the
