Abstract
This invention is directed to system and methods for the oxygenation of the blood of a patient, comprising an extracorporeal blood circulation path adapted to be coupled to the patient's vascular system, and comprising apparatus for oxygenating blood flowing therein and withdrawing CO2 therefrom, wherein the flow rate of blood flowing in said extracorporeal blood circulation path does not exceed ⅖ of the patient's blood flow. The extracorporeal blood circulation path preferably comprise a cartridge including an oxygenator and at least one cannula.
Claims32
A system for the oxygenation of the blood of a patient, comprising an extracorporeal blood circulation path adapted to be coupled to the patient's vascular system, and comprising apparatus for oxygenating blood flowing therein and withdrawing CO2 therefrom, wherein the flow rate of blood flowing in said extracorporeal blood circulation path does not exceed ⅖ of the patient's blood flow.

A method of increasing blood oxygenation level and CO2 removal in a patient capable of spontaneous breathing, the method comprising:
- introducing a first cannula into a first blood vessel for draining blood therefrom, and a second cannula into a second blood vessel for infusing oxygenated blood thereto, the first and second cannulas being linked to an extracorporeal blood oxygenation system through a first flow line and a second flow line, respectively, and circulating said patient's blood at a circulation rate of no more than about 30 ml/Kg per minute through said extracorporeal blood oxygenation system to oxygenate said blood and obtain CO2 removal from the blood and an increase in blood oxygenation level of the patient.
