Acknowledgements Quality Control Body-mounted blast overpressure sensor data analysis for the INVICTA program Funding: Defense Health Agency Using high-fidelity CFD simulations, for reconstructing blast environments provide valuable information. It can determine how positioning, orientation, and environment affect the blast exposure on personnel in combat training. The calculation values can be used to understand overpressure exposure, mitigate exposure where possible, and can be correlated with ongoing research to address concerns associated with medical outcomes. Collected exposure data included Range Safety Officers (RSO) and trainees (subjects) in combat training scenarios. A total of 64 participants were analyzed , including 11 RSO and 53 trainees. The total number of gauge triggers for all subjects is 1,529. The number of “good” waveforms is 1,114. Taking exposure locations one step further, ARA has looked at specifically the head location and compared to the peak overpressure values. R003 has the highest values at 14 psi with 11 exposures. R008 has the lowest exposure count as well as the lowest peak overpressure value. Understanding blast exposure is important for protecting our service members. Body-mounted blast overpressure sensors are used to quantify blast exposure magnitude and frequency on personnel in combat training. Through the Investigating Training Associated Blast Pathology (INVICTA) program, the collection and analysis of body-mounted blast sensor information was used to better understand blast exposure on personnel and correlate with medical outcomes specifically Traumatic Brain Injury (TBI). Background RSO/Trainee Results RSO/Trainee Results Blast overpressure data was collected with Blast Gauges (BG) by BlackBox Biometrics worn in sets of three on the body: head (nape of neck), chest, and non-firing shoulder. The BG records overpressure exposure data on the subjects and a date and time stamp. When worn during combat training, the gauges reco, RITM0028170, Understanding blast exposure is important for protecting our service members.
