centrifugal pump cardiopulmonary bypass|indications for cardiopulmonary bypass : agent 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 The speed torque curve characterize a centrifugal pump. The theoretical characteristic is a parabola starting from the origin and proportional to the square of the speed. The torque can be expressed as. T = k n 2 (1) where . T = torque .

Cardiopulmonary bypass (CPB) is a technique commonly used in operations or surgical procedures involving the heart. The technique allows the surgical team to oxygenate and circulate the patient's blood, thus allowing for the temporary bypass of the heart and lungs. One of the key components of a cardiopulmonary bypass system is the centrifugal pump, which plays a crucial role in maintaining blood flow during the procedure.

Cardiopulmonary Bypass Explained
Cardiopulmonary bypass is a procedure that temporarily takes over the function of the heart and lungs during cardiac surgery. It involves diverting the patient's blood away from the heart and lungs, oxygenating it, and then returning it to the body. This allows the surgical team to perform complex procedures on the heart while maintaining blood flow to the rest of the body.
Cardiopulmonary Bypass Procedure Steps
The cardiopulmonary bypass procedure typically involves the following steps:
1. **Cannulation**: The surgical team inserts tubes called cannulas into the patient's blood vessels to divert blood to the bypass machine.
2. **Initiation of Bypass**: The blood is then diverted to the bypass machine, where it is oxygenated and circulated using a pump.
3. **Monitoring**: The patient's vital signs, including blood pressure and oxygen levels, are closely monitored throughout the procedure.
4. **Decannulation**: Once the surgical procedure is complete, the patient is gradually weaned off the bypass machine, and the cannulas are removed.
Cardiopulmonary Bypass Machine Diagram
A cardiopulmonary bypass machine consists of several components, including:
1. **Centrifugal Pump**: The pump responsible for circulating the patient's blood during the bypass procedure.
2. **Oxygenator**: A device that oxygenates the blood and removes carbon dioxide.
3. **Heat Exchanger**: Maintains the temperature of the blood as it circulates through the machine.
4. **Tubing**: Connects the various components of the bypass machine.

What is a Cardiopulmonary Bypass?
A cardiopulmonary bypass is a technique used during cardiac surgery to temporarily take over the function of the heart and lungs. It allows the surgical team to perform intricate procedures on the heart while maintaining blood flow to the rest of the body.
Indications for Cardiopulmonary Bypass
Cardiopulmonary bypass is indicated in a variety of cardiac surgical procedures, including:
1. **Coronary Artery Bypass Grafting (CABG)**
2. **Valve Replacement Surgery**
3. **Heart Transplantation**
4. **Congenital Heart Defect Repair**
Cardiopulmonary Bypass Machine Cost
The cost of a cardiopulmonary bypass machine can vary depending on the manufacturer, model, and features included. However, these machines are a significant investment for hospitals and surgical centers due to their critical role in cardiac surgery.
Basics of Cardiopulmonary Bypass
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
Investigations regarding the relation of noise performance for centrifugal pump operating in pump and turbine modes continue to be inadequate. This paper presents a series of comparisons of flow-induced noise for both operation modes. The interior flow-borne noise and structure modal were verified through experiments. The flow-borne noise was calculated by .The sound of a centrifugal pump varies in intensity along its H/Q curve depending on the operating point. To conserve energy and minimise noise, pumps should generally be run at the operating point that provides optimum pump efficiency. Noise is usually lowest when the .
