Trauma patient hemorrhage control including rapid autotransfusion

Abstract

A method for onsite hemorrhage control in trauma patients using a portable rapid autotransfusion device can involve recovering a first portion of patient blood from an extravascular space into a fluid reservoir of the device. A negative internal pressure can be applied to the blood. The blood can be conditioned, such as by oxygenating and removing carbon dioxide. The conditioned blood can be returned to the patient intravenously at a rate that matches the rate of blood recovery, ensuring that the net volume of returned blood is maintained substantially equal to the net volume of removed blood.
