Hemorrhage
Conditions
Brief summary
Rapid infusion of blood is needed occasionally for control massive bleeding. For rapid infusion, external pressure can be used. The investigators will study correlation between external pressure and hemolysis and deformability of red blood cell.
Detailed description
Rapid infusion of blood is needed occasionally for control massive bleeding. For rapid infusion, external pressure can be used which cause hemolysis and alteration of red blood cell. The investigators will study correlation between variable external pressure and hemolysis and deformability of red blood cell. Differ from previous study, the investigator will use scanning electron microscope for observation red blood cell.
Interventions
Blood pass through infusion set without external pressure.
Blood pass through infusion set under external pressure (150mmHg)
Blood pass through infusion set under external pressure (200mmHg)
Blood pass through infusion set under external pressure (250mmHg)
Blood pass through infusion set under external pressure (300mmHg)
