CarbonAid™
CO2 insufflation into the cardiothoracic wound cavity with the CarbonAid™ carbon dioxide diffuser markedly decreased the number of microemboli in the left atrium, left ventricle, and ascending aorta during open-heart surgery.1 (Circulation 2004;109:1127-32)
Carbonaid, a carbon dioxide disffuser, improves total cardiac surgical care for patients undergoing heart valve replacement surgery
The CarbonAid™ carbon dioxide diffuser has been shown to be the most effective device for de-airing of the cardiothoracic cavity and is the only reported device that stays efficient even when wet.2,3
The attached bacterial filter protects against unintentional bacterial contamination from the CO2 source.
The CarbonAid™ carbon dioxide diffuser allows for a high laminar outflow of CO2 at a low outflow velocity. By avoiding turbulence, it creates a total CO2 atmosphere within the wound cavity,4,5 thus eliminating any risk of air embolism.
