Early Detection of Chemical Warfare Exposure
With the threat of chemical, biological, radiological, and nuclear weapons increasing with modern technology and drone warfare, early detection is key to combat these dangers. Continuous monitoring can provide the real-time information to alert a warfighter or first responder about potential exposure risk before the threat becomes critical.

AI-enabled detection
AI algorithms use multiple signals to detect and uniquely identify:
-
Opioids
-
Organophosphates
-
Mustard Agents


A suite of AI tools enables unparalleled accuracy and timely detection of a possible chemical agent exposure in preclinical testing using simulated warfare agents.

Exposure Detection in Action
Combining the inputs from three sensor signals plus relative values, ratios, and trends powers a robust exposure detection algorithm. Twenty-six sensors were used across 13 preclinical subjects. All exposure events were detected and all were correctly identified as opioid, organophosphate simulant or mustard agent simulant exposure.



Why is Tissue Measurement Better?
PercuSense tissue oxygen measurement provides an opportunity for unparalleled detection of any event that impacts circulation, including chemical exposure, acute illness, and trauma.
Tissue Oxygen
Measures oxygen levels in tissues, depending on local blood flow
Shows a sharp and immediate drop because opioid exposures and other events reduce peripheral circulation
Recovers once perfusion is restored, making it the most sensitive indicator of circulatory effects
1
Venous Oxygen
Drops significantly after opioid exposure or trauma because reduced circulation leads to increased oxygen extraction by tissues
2
Pulse Oximetry
Measures oxygen saturation in the arterial blood
Remains relatively stable initially because arterial blood is oxygenated by lungs before it reaching tissues
