4. Book reviews Artificial Organs and Cardiopulmonary Support Systems By Felix;Rapaport, T.; Merrill, John P.,1972
5. This book is reprinted from Transplantation Proceedings and covers a symposium on the use of artificial support systems, particularly with a view to holding patients for transplantation. It does concentrate on cardiac support and the problems of longterm extracorporeal bypass and artificial hearts, but artificial respiration and a number of unrelated support systems are also briefly covered. The present state of artificial heart and lung support is extensively covered, and for those concerned in the problems there is useful upto-date material. Many of the conclusions reached will probably be soon outdated so that this is unlikely to remain a useful reference book for more than a very few years in a developing speciality
