Clinical experience with the Teflo disposable membrane oxygenator.
A simple, inexpensive, highly efficient disposable membrane oxygenator with low priming volume and a microporous membrane recently has become available. Animal and clinical investigations of its use have been most satisfactory, and clinical experience now has been extended to include 285 patients. Its primary advantage has been the ability to control oxygenation and carbon dioxide separately. Disadvantages have included the somewhat increased complexity of the system as compared with bubble oxygenator systems, the necessity of converting pumps for its use, and excessive condensation of water vapor in the gas phase of the oxygenator unless certain precautions are followed.
