Bubble oxygenator - Wikipedia
A bubble oxygenator is an early implementation of the oxygenator used for cardiopulmonary bypass. It has since been supplanted by the membrane oxygenator [ 1 ] as a result of advances in material science.

Gibbon began developing the heart-lung machine in 1937 to permit open-heart surgery. He designed a system in which anticoagulated blood was directly exposed to oxygen (‘film’ or ‘ bubble oxygenators ’).
Principles of Oxygenator Function: Gas Exchange, Heat Transfer, …
Jun 7, 2016 · It is this principle that allows gas bubbles to come out of solution in the blood during depressurization, as when scuba divers get “the bends” from too rapid an ascent from diving.
Comparisons of measured and calculated data in the immediate postperjusion interval showed 110 differences between bubble and membrane oxygenator subsets for short perfusions.
in oxygen consumption in surface-cooled hypothermic animals, Gollan reasoned that metabolic stability under these conditions could be readily provided with substan-tially lower ECC flow rates. He and his colleagues under-took a series of investigations using a bubble-oxygenator and what proved to be a key technical advance: a heat
Oxygenators for extracorporeal circulation: theory and practice ...
Jan 1, 2023 · There are three essential features of the bubble oxygenator: a multiperforated disk, a coalescence (“de-foaming”) chamber, and a combined bubble trap and oxygenated blood residence component (Fig. 13.3A) [13]. In this system, oxygen under pressure was dispersed through the porous disk into a venous blood column that instantly created ...
Membrane oxygenators have numerous theoretical advantages over bubble oxygenators for extracorporeal circulation. Although various potentially beneficial bio-logic differences have been observed between mem-brane and bubble oxygenators in cardiac operations, the clinical importance of these differences is still unresol-ved.
Brief Bubble and Intermittent Surface Oxygenation Is a Simple and ...
Jun 11, 2020 · Bubble and intermittent surface oxygenation might be an easy alternative for membrane oxygenation eliminating the need for a membrane oxygenator and therefore reducing the total costs of oxygenated machine perfusion and making air transport easier.
bubble oxygenator - Medical Dictionary
bubble oxygenator a device in which pure oxygen is bubbled through an extracorporeal reservoir of blood, either directly or through a filter. film oxygenator a device, encased in a container of oxygen, that makes possible reduction of a thin film of blood to facilitate the exchange of gases.
In the design of disposable bubble oxygenators, these con-cepts can be used to increase the mass transfer of oxygen. If oxygen enters a column of blood in an uncontrolled fashion and forms bubbles of varying size which then pass through the column at random, low oxygen transfer efficiency results.
