BACKGROUND Markers of temporal changes in central blood volume are required to non-invasively detect hemorrhage and the onset of hemorrhagic shock. Recent work suggests that pulse pressure may be such a marker. A new approach to tracking blood pressure, and pulse pressure specifically is presented that is based on a new form of pulse pressure wave analysis(More)
BACKGROUND There is a significant need for continuous noninvasive blood pressure (cNIBP) monitoring, especially for anesthetized surgery and ICU recovery. cNIBP systems could lower costs and expand the use of continuous blood pressure monitoring, lowering risk and improving outcomes.The test system examined here is the CareTaker® and a pulse contour(More)

Reflective exercise (RE), a westernized form of Qigong, combines meditation, breathing, and targeted mental attention to an internal pulsatile sensation, previously shown to protect varsity(More)
One of the most commonly identified precipitant of seizures for people with epilepsy is stress. We have developed a system for tracking objective measures in the subjects homes. An integrated system is used for data collection, uploading, and viewing the data. Our system is currently deployed and actively collecting data from people suffering from epilepsy(More)
