Work in collaboration with Flashback Technologies and researchers from the US Army Institute for Surgical Research (USAISR) to extract features to detect and predict conditions such as blood loss, intercranial pressure and seizure from noninvasive measurements including ECG, ICG, TCD, EEG, SP02, and continous BP. We have integrated the CiperSensor with the BMEYE Nexfin continuous blood pressure monitor. We are currently working with Sotera Wireless on hardware and software integration of our algorithms with their ViSi device.

Researchers at USAISR study hypovolemia using Lower Body Negative Pressure (LBNP) to bring human subjects to the point of cardiovascular collapse. LBNP (see image below) applies increasing levels of negative pressure to the lower extremities over time pulling blood away from the heart and lungs. Noninvasive physiologic signals are measured at the same time to determine which sensors are effective predictors of blood loss.

We analyze the subject LBNP and sensor dataset to identify patterns and attributes of the signals which best facilitate prediction of blood loss and physiologic reserve, with the goal of building noninvasive sensors for blood loss which can be easily deployed in a combat casualty setting.
