Multi-Parameter Physiological Monitor

There is a critical need for a next generation physiological monitors that can be used to determine the health of the warfighter in the field. Conventional vital signs monitors are typically large, and require a number of cables from the measurement unit to be attached to the patient. It is thus impractical for the warfighter to wear conventional vital signs monitors in the field. It is also impractical for a medic or corpsman to carry the conventional units in the field and attach the various sensors to the warfighter, and manage the cables during transport of the patient. Linea Research Corporation proposed to develop a physiological monitor based on photoplethysmographic techniques that will continuously monitor the heart rate, heart rate variability, beat-to-beat blood pressure, blood oxygen saturation and skin temperature. The unit will compact and wearable, allowing the continuous monitoring of the physiological data through a wireless interface. The monitor unit will provide a self alignment feature that will allow minimally trained personnel, or the warfighter himself, to attach the device to the upper arm. Once the device is attached, it can be worn continuously during field operations or during medical transport from the field to the hospital.
