A non-contact hemodynamic status and location system

Noninvasive Medical Technologies, Inc. (NMT) is developing an innovative decision-making system of systems that consists of a wireless sensor for monitoring vital hemodynamic and pulmonary parameters including cardiac output, heart rate, and respirations. This sensor is coupled with a location sensor, and a multi-sensory display device that uses adaptive, ldquosmartrdquo software to provide the right information at the right time by the right sensory channel(s) to a first responder using multi-modal data integration and visualization techniques. Hemodynamic monitoring using either a catheter or electrodes has been recognized as the standard for care but has been limited to the hospital setting. The noinvasive NMT system is not as restricted. The NMT system is a continuous hemodynamic monitoring device that uses radio frequency impedance interrogation (RFII) to measure thoracic bio-impedance and then using a cardioplethysmograph algorithm, measures and trends the heart rate, respiration rate, cardiac output, and an evidence-based life score rating. Because RFII technology is packaged in a small device with very low power requirements; noninvasive, continuous, and intelligent intermittent hemodynamic monitoring can be extended beyond the hospital emergency room to the medical first aid arena. Coupled with location sensors and displays to form a combat casualty care management systems, it allows combat medics to locate casualties, prioritize severity of injuries, and triage efficiently from a remote and safe location. Transitioning the system from the combat environment to other hazardous situations like the underground mining environment, presents new opportunities as well as challenges. Mining or other operations in extreme environments requires the best clinical decision-making under the worst conditions, and it is critical to develop improved decision making resources that will protect workers and provide a safer work environment. Understanding the physiologic perf- ormance degradation of the rescuers during activity and employing a system to the team captain on the surface to track the physical condition of the rescue team without intruding into the rescue process or delaying the mission allows rescue operations to proceed efficiently, safely, and rapidly.
