Clinical experience with the Teflo disposable membrane oxygenator
AC Beall Jr, RT Solis, M Kakvan, GC Morris Jr, GP Noon and ME DeBakey
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.
