Ex-Vivo Lung Perfusion (EVLP) has allowed lung transplantation in humans to become more readily available by enabling the ability to assess organs and expand the donor pool. Here, we describe the development of a rat EVLP program and refinements that allow for a reproducible model for future expansion.

Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN Capacitors (C), inductors (L), and resistors (R) are each an important circuit element with distinct behaviors. A resistor dissipates energy and obeys Ohm's law, with its voltage proportional to its current. A capacitor stores electrical energy, with its current proportional to the rate of change of its voltage, while an inductor stores magnetic energy, with its voltage...

FAQs
The pump generates the blood flow required to move blood through the extracorporeal pathway, while the oxygenator regulates oxygen and carbon dioxide exchange. Their coordinated operation supports circulation and gas exchange during procedures requiring controlled perfusion. Monitoring ports and pressure measurements help assess whether flow through these components remains reliable during use.
Priming fills the pathway with fluid, and de-airing removes trapped air from the tubing and connected components. These steps establish a continuous fluid-filled route before operation and reduce risks associated with air within the circuit. Careful preparation also helps confirm that the pathway is ready for controlled blood flow and gas exchange.
Tubing, the reservoir, pump, oxygenator, filters, and monitoring ports each contribute to circuit performance. Their selection and connection determine how fluid moves, how gas exchange is supported, and how pressure or other operating conditions can be observed. Matching components appropriately helps reduce the likelihood of inadequate flow, impaired gas exchange, leaks, or clot formation.
Leak testing identifies failures in the assembled fluid pathway before clinical use, while pressure monitoring provides information about operating conditions during perfusion. Together, they support early recognition of circuit problems that could compromise flow or system integrity. These checks complement sterile technique and help promote reliable operation during cardiopulmonary bypass and related interventions.
Preparation begins by assembling the tubing, reservoir, pump, oxygenator, filters, and monitoring ports in the intended flow pathway. The circuit is then primed and de-aired, followed by leak testing and confirmation of pressure-monitoring capability. Sterile technique is maintained throughout, and the completed setup is checked for conditions that could impair flow or gas exchange.
Perfusion circuit setup is particularly relevant to cardiopulmonary bypass and related interventions in which circulation and gas exchange require extracorporeal support. A prepared circuit allows clinicians to maintain controlled blood flow while the oxygenator regulates oxygen and carbon dioxide exchange. Reliable assembly and monitoring help reduce risks from air, clot formation, inadequate flow, or impaired gas exchange.
