Early detection of ongoing occult hemorrhage (OH) before onset of shock is a universally acknowledged unmet need in both trauma and surgery. Delays in the detection of OH are associated with a “failure to rescue” and a dramatic deterioration in prognosis once the onset of clinically frank shock has occurred. Death from hemorrhage occurs in approximately 60,000 patients each year in the United States, with trauma accounting for most cases. But postpartum hemorrhage, gastrointestinal bleeding, perioperative hemorrhage, and rupture of aneurysms account for thousands of other lives-lost and billions of dollars in medical costs.
Early in systemic disease, there is not robust enough signal-to-noise characteristics in single measurements taken at single locations. Put another way, “there’s not enough information in the measurement of tissue oxygen at your fingertip to allow doctors and nurses to make an early decision that you’re getting sicker…”
We utilize a broad array of existing noninvasive technologies to acquire multiple signals, and we do it in multiple anatomic locations. Our wearable sensors may look simple - but the total data acquired by our system is orders of magnitude greater than previous devices or currently marketed units. State-of-the-art “deep learning” knits together this vast data set into a usable algorithm.
Each Multivariate Systems device is a multitechnology-multiplex-electro-optical noninvasive system that continuously monitors patients and alarms when its algorithms detect progression of disease. The system is highly sensitive but with a low false positive rate. Our vision is this -- that medical personnel could apply the wearables and turn on the device, and then focus their effort on the already unstable patients, secure in the knowledge that our device will alarm if their stable patient deteriorates.
