Increasing the Resolution of Simulated Combat Trauma Injuries in a High Level Architecture (HLA) Environment.

Abstract

This research develops a technique that leverages Operational Requirements-based Casualty Assessment (ORCA) generated patient conditions for use in the Combat Trauma Patient Simulation (CTPS). The research paves the way for enhancing the resolution of combat trauma injuries in a High Level Architecture (HLA) environment. ORCA is U.S. Government-owned software developed by the Crew Casualty Working Group (CCWG). The ORCA methodology calls for the initial creation of a "medical casualty" in order to determine the affects on the body's ability to perform certain military tasks. The Alpha + version upon which this paper is based had working modules for only five of seven planned injury-inducing insult types. These are Penetrators (fragments), Blast overpressure, Thermal fluence, Toxic gases (military agents), and Directed Energy. The CTPS research team is prototyping and evaluating a training and analysis HLA federation that realistically simulates the emergency medical treatment process from the time of injury through initial treatment at a field hospital. The goals of the project are to decrease the deaths due to combat wounds by having better trained medical staffs and to provide a mechanism for analysis and for test and evaluation (T&E) of issues in casualty medical treatment. In addition to ORCA, a central component of this system is a physical simulation of a casualty (an instrumented mannequin), the Human Patient Simulator (HPS). Products of this research include a methodology and techniques for generating ORCA injuries and storing the injury profiles offline in a database. This database can later be read by CTPS to enhance the injury data available on a given casualty. Future work can automate this process. This research also discusses a prototype injury Simulation Object Model (SOM), that objectifies the ORCA output data. Additionally, a prototype Federation Object Model (FOM) is presented.
