Triage&
Monitoring
3
Key concepts
90% of potentially salvageable casualties exsanguinate
Rapid evacuation & treatment as main objectives
Prioritizing is a key concept of point of injury care
Early detection of hemorrhage is crucial
The gap with currently available Indices
Volume of blood lost
Desired vital sign
Available vital signs
Triage criteria limitations
• Assessment of physiological reserve
• Non-invasive recording & analyzing of the arterial waveforms
using machine learning techniques.
• Ranges from 0 (complete decompensation) to 1
• Has been shown to correlate with central blood volume loss in
laboratory conditions1
• Not operator dependent, Small and non-invasive device
The Compensatory Reserve Index (CRI)
