Abstract
A gas-enriched fluid is provided by the combination of a first fluid, such as a patient's blood, with a second gas-supersaturated fluid, such as an oxygen supersaturated fluid. In this example, a catheter assembly includes a portion that receives the patient's blood from a pump and that receives the oxygen supersaturated fluid from an appropriate fluid source. The oxygen supersaturated fluid is advantageously combined with the blood in an area of laminar flow, and then this gas-enriched fluid is delivered to the patient through an appropriate lumen coupled to the portion of the catheter assembly.
