Abstract
A method for a bubble-free oxygenated blood delivery is provided. The method includes a step of selecting a delivery system having a tubular elongated member with a lumen. The selecting step comprises determining an effective diameter of the lumen needed to achieve a bubble-free delivery of the oxygenated blood based on a specified oxygenated blood flow rate and a desired target oxygen partial pressure in the oxygenated blood. The delivery system includes a generally tubular elongated member having a proximal end portion, a distal end portion, and a transition portion located between the proximal end portion and the distal end portion. The transitional portion is relatively flexible compared to the proximal end portion and is relatively stiff compared to the distal end portion. In another embodiment, the delivery system includes a generally tubular elongated member having a proximal end portion and a distal end portion with a plurality of holes.
