perfusion techniques

Perfusion techniques involve transferring blood or a replacement fluid through tissues or organs to keep them alive and functioning, often during surgery or in critical care. These methods maintain oxygen and nutrient delivery while removing waste, ensuring tissues stay healthy. For example, during heart surgery, a machine temporarily takes over the heart and lung functions, allowing surgeons to operate safely. Perfusion can also be used for organ preservation, such as keeping a donor kidney viable for transplantation. Overall, these techniques are vital for supporting organ health and function when natural blood flow is interrupted or needs assistance.
