Fabrication of the intravascular oxygenator and exploration of its bionical characteristics

Objective: In order to study the oxygenation mechanism of intravascular oxygenator（IVOX） and improve its practical efficiency Methods: A new IVOX was fabricated using polypropylene hollow fiber membrane and its efficacy was chacked on 9 experimental dogs Results: In vivo experimental testing of IVOX, arterial blood gas was improved in acute hypoxic and hypercapnic dogs The IVOX could increase PaO₂ 4.06 kPa（P＜0.01）,and decrease PaCO₂ 1.99 kPa（P＞0.05） Conclusion: The new form of IVOX seems to be sucessful in improving hypoxic and hypercapnia but it is nessesary to further improve its efficiency along with bionics
