Gas Exchange in the Rygg-Kyvsgaard Bubble Oxygenator

Gas Exchange in the Rygg-kyvsgaard Bubble Oxygenator.

The Rygg-Kyvsgaard oxygenator employed in extracorporeal circulation (Fig. 1) was designed on the basis of experience gained from experimental operations on dogs (Rygg, Engell, and Kyvsgaard, 1956; Rygg and Kyvsgaard, 1957; Gammelgaard, Husfeldt, and Therkelsen, 1957; Rygg and Kyvsgaard, 1958; Rygg, 1958). However, in experimental operations the opportunities of assessing its oxygenation and ca...

Adult Perfusions using Rygg-Kyvsgaard Oxygenators

INTRODUCTION Rygg-Kyvsgaard oxygenators have been in constant clinical use for the past 15 years. • 2 ' 3 ' 4 ' 5 • 6 • 7 ' 8 • 9 • 10 The Harvey oxygenator is a new generation of disposable lung, based on an established principle, which incorporates an integral heat exchanger.n· 12 It was felt that a clinical comparison of a well established device with a new generation device would prove both...

Inexpensive heat-exchanger system for the Rygg bag oxygenator.

A clinical evaluation of the Rygg-Kyvsgaard III and the mark II pump oxygenators.

In the Departments of Surgery D and R of the University Hospital of Copenhagen (Rigshospitalet) two pump oxygenators of different types, namely, the Rygg-Kyvsgaard III bubble oxygenator and the mark III screen oxygenator, have during the last two years been used in two parallel series of perfusions. An opportunity has thus been provided for comparing the efficacies of the two oxygenators. Since...

The transition from the bubble oxygenator to the microporous membrane oxygenator.

The transition from bubble oxygenators to microporous membrane oxygenators is a good example of how industry working with customers and material suppliers can help improve a surgical technique, such as cardiopulmonary bypass. The development is characterized by many individuals who, through their inventiveness and determination, made the transition possible. While the medical personnel involved...
