Researchers from many disciplines, with both basic and clinical perspectives, came together in this volume to review and debate issues pertaining to the investigation and control of tissue oxygenation in acute medicine, as well as treatments to improve tissue oxygenation when abnormal. In this latter context, special emphasis is placed on understanding the effect of blood substitutes on the circulation and on the potential roles of this family of compounds in clinical medicine.
