Smart Hemodynamic Monitoring System for Critical Care Air Transport Team (CCATT)

Aeromedical evacuation (AE) involves prolonged transport of injured warfighters at risk for clinical deterioration under austere medical conditions. Because of their injuries they have a high potential for progression of recognized and/or occult additional injuries leading to acute instability during Critical Care Air Transport Team (CCATT) transfer. While the CCATTs have a great depth of medical experience in aeromedical evacuation of critically injured warfighters, their care can benefit from additional direct hemodynamic and neurologic information to complement that obtained through normal medical monitoring, specifically Propaqs. Active Signal Technologies proposes to employ passive acoustics to track patient condition in this severe environment and provide alerts to the CCATT when a condition changes and the patient requires additional and immediate medical attention. Specifically, the system will build upon a hand held PDA based system now under test at the R Adams Cowley Shock Trauma Center to monitor both resuscitation status and brain perfusion. It will have the capability of hemodynamic stability and neurologic status monitoring and will use a data base of perfusion status signal analysis accumulated over a period of 8 years to help interpret the data gathered by the CCATT.
