Clinical experience of Bentley hollow fiber oxygenator BOS CM40

Abstract

Bently hollow fiber oxygenator BOS CM40 was used for open heart surgery in 7 adult patients and compared with TMO in 8 patients. The following results were obtained. 1 Blood-gas analysis data of BOS showed higher PaO₂ and lower PaCO₂ than that of TMO with same condition.
2 At the end of bypass, platelet count in BOS showed lower value than that in TMO. But immunoglobulin was maintained well, complement value was higher than that in TMO throughout bypass, too. 3 Plasma free hemoglobin levels were almost same in BOS and TOM. 4 Oxygenator pressure drop in BOS showed slightly high compared to that in other plate membrane oxygenators.
