The gas transfer characteristics and gaseous microemboli (GME) production of five different bubble oxygenators (Polystan Venotherm, Harvey H-1700, Bentley BIO-10, Gambro 10 and Shiley S-100A HED) and one membrane oxygenator (Cobe CML) have been assessed during standardized clinical perfusion for open-heart surgery in 60 adult patients. The perfusionist attempted to maintain physiological levels of PaCO 2 (5 ± 1 kPa) and PaO2 (12 ± 2 kPa). Only 3% of blood gas values were within the normal range…

A clinical evaluation of the performance characteristics of one membrane and five bubble oxygenators: haemocompatibility studies
TLDR
When selecting the oxygenator for use in patients undergoing open-heart surgery, gas transfer characteristics and GME production together with the superior preservation of platelet numbers and function in the membrane oxygenator group and variable degree of platelets depletion and reduction in platelet aggregability demonstrated in the five bubble oxygenator groups, must be taken into account.
A clinical evaluation of the Bentley 10B and Bentley 10Plus bubble oxygenators
During clinical hypothermic cardiopulmonary bypass (CPB) in 20 adult patients, the ability of the perfusionist, using an alphastat acid-base blood gas management technique, to control blood gas…
Haemocompatibility of membrane and bubble oxygenators
TLDR
During clinical hypothermic cardiopulmonary bypass (CPB), the haemocompatibility of six groups of membrane oxygenators has been studied in 60 patients having open-heart surgery and Membrane oxygenators manifestly must be the oxygenator type of choice for clinical CPB.
Clinical evaluation of the gas transfer of the Bentley 10 Plus bubble oxygenator during alpha-stat regulated hypothermic cardiopulmonary bypass
TLDR
The results of this study demonstrate that the correct use of the Bentley 1 0 Plus• bubble oxygenator during alpha-stat regulated hypothermic (26-30°C) CPB allows control of the Pa02 and PaC02 levels within preset ranges.
Determination of significant differences in performance of the Bentley BOS-CM 40 hollow fibre membrane oxygenator and the Polystan VT5000 venotherm bubble oxygenator
Ten mongrel dogs were connected to cardiopulmonary bypass by cavoaortic cannulation, classic roller pump and either Bentley BOS-CM 40 hollow fibre membrane oxygenator or Polystan VT5000 Venotherm…
Evaluation of a range of extracorporeal membrane oxygenators
TLDR
This study deals with the membrane oxygenator group which typically consists of ’sheet’ and hollow-fibre oxygenators and concludes that there are some considerable advantages to be gained from the use of these devices when compared to the more traditional bubble oxygenators.
Experimental evaluation of the Dideco Masterflo paediatric hollow-fibre membrane oxygenator
TLDR
Nine mongrel dogs connected to cardiopulmonary bypass byfemorojugularvenous and femoral arterial cannulation, classic roller pump and the integrated Dideco D702 Masterflo hollow-fibre membrane oxygenator showed physiologic values and no evidence of major lung trauma or pulmonary oedema in relation to the six hours' bypass.
Air handling characteristics of five membrane oxygenators
TLDR
The potential of membrane oxygenators to allow passage to clinical quantities of air into the arterial line is demonstrated, and it is demonstrated that the top to bottom flow feature offers protection against passage of air at low flow rates only, while a simple valve is quite effective in preventing passage ofAir at a wide range of clinically relevant flow rates.

Determination of significant differences in performance of the Bentley BOS-CM 40 hollow fibre membrane oxygenator and the Polystan VT5000 venotherm bubble oxygenator
TLDR
Ten mongrel dogs were connected to cardiopulmonary bypass by cavoaortic cannulation, classic roller pump and either Bentley BOS-CM 40 hollow fibre membrane oxygenator or Polystan VT5000 Venotherm bubble oxygenator for eight hours, with mean flow rate of 100 ml/kg min.

TLDR
Minimal mean arterial pressures are essential to maintain good function of all organ systems for many hours of perfusion and to avoid disseminated intravascular coagulation by keeping capillary beds open.
