What It Is

The Affinity NT Hollow Fiber Oxygenator is a medical device used in cardiopulmonary bypass procedures. It utilizes a hollow fiber membrane to facilitate gas exchange, providing oxygenation and carbon dioxide removal during surgery.

Clinical Applications

Commonly used in cardiac surgeries requiring cardiopulmonary bypass, such as valve replacements and coronary artery bypass grafting. It is particularly useful in managing patients with high oxygen demands.

Evidence Summary

The literature includes three studies from 2002 to 2014, comprising case reports and comparative evaluations. These studies assess the device's performance in oxygen delivery and pressure drop.

Reported Outcomes

Published studies report that the Affinity NT Hollow Fiber Oxygenator effectively meets oxygen needs, even in patients with high body mass indices. It demonstrates a low transoxygenator pressure drop, comparable to other leading oxygenators.

Safety Profile

Reported complications include potential hemolysis and platelet damage due to trans-membrane pressure drop, although specific adverse events were not detailed in the studies provided.

Evidence Limitations

The evidence is limited by the small number of studies and lack of large-scale randomized controlled trials. Further research is needed to explore long-term outcomes and safety in diverse patient populations.
