Circulatory support refers to medical interventions that help maintain or improve blood flow and oxygen delivery to the body's tissues. This is crucial for patients with heart conditions or those undergoing surgery, as their hearts may not pump blood effectively. Techniques can include medications, mechanical devices, or surgical procedures designed to assist the heart's function. Common methods of circulatory support include the use of intra-aortic balloon pumps and ventricular assist devices. These devices can temporarily take over the heart's pumping action, allowing it to rest and recover. Proper circulatory support can significantly enhance patient outcomes and recovery times.
