Heart pump and oxygenator.
1124 T ms PAPER is a general review of the development of the artificial heart-lung to facilitate open-heart surgery. At the close of World War II many centers began investigating the possibility of total cardiac bypass. Oven the past decade, pump oxygenerators of various types have become popular and recent clinical successes throughout the world have given further impetus to the study of prob...
متن کاملVariations in the Circuit of a Pump-oxygenator.
S INCE THE ADVENT OF OPEN-HEART SURgery , surgeons and pump-oxygenator technicians have striven to niake their work more simple, yet remain within safe boundaries. The purpose of this paper is to present two details we have adopted in our pump-oxygenator circuit. In many pump-oxygenators, the venous blood from the patient is returned to the top of a venous reservoir where it then falls down int...
متن کاملStudies in extracorporeal circulation. I. Applicability of Gibbon-type pump-oxygenator to human intracardiac surgery: 40 cases.
BASIC laboratory studies on the extracorporeal circulation and oxygenation of blood began many years ago. In 1939, Gibbon 11 reported his pioneering work with perfusion of the entire body during the temporary functional exclusion of the heart and lungs from the remainder of the circulation. Since then, investigative work has progressed along many lines, one of which has been directed toward the...
متن کاملChanges in sevoflurane plasma concentration with delivery through the oxygenator during on-pump cardiac surgery.
BACKGROUND It is unclear what factors affect the uptake of sevoflurane administered through the membrane oxygenator during cardiopulmonary bypass (CPB) and whether this can be monitored via the oxygenator exhaust gas. METHODS Stable delivery of sevoflurane was administered to 30 elective cardiac surgery patients at 1.8 vol% (inspiratory) via the anaesthetic circuit and ventilator. During CPB,...
متن کاملMembrane Oxygenator with a Built-In Hemoconcentrator
In order to facilitate the handling of cardiopulmonary bypass (CPB) and simplify the circuit, we have developed a new membrane oxyganator with a hemofiltration function. The hollow fiber units for gas exchange and hemofiltration were combined in concentric circles in a cylindrical housing. The total priming volume was 190 ml. Because we used a silicon-coated hollow fiber membrane for gas exchan...
