This new system is currently being tested on medical helicopters in the Boston area, and it is also a rather simple one since it comprises of no more than your standard patient monitor which will keep track of the heart and respiratory rates, in addition to other details such as blood pressure, where it will remain connected to a computer that does all of the data processing.
Known as APPRAISE (Automated Processing of the Physiological Registry for Assessment of Injury Severity), this system is currently undergoing testing at the Massachusetts General Hospital (MGH) alongside another two trauma centers, in addition to the U.S. Army and Boston MedFlight, the air ambulance service.
