Technical considerations in the use of the membrane oxygenator (Lande'-Edwards) for open heart surgery

Experience has shown that successful cardio-pulmonary bypass depends upon an efficient oxygenator which causes minimum blood damage. Experience with 1,600 Lande'-Edwards membrane oxygenators in more than 1,000 patients has led to the development of a simple and safe routine for their use in open heart surgery. The circuitry, method of preparation for perfusion, and management of perfusion are described in detail.
