Detect Hemorrhage Before Vital Signs Change

The CipherOx CRI-M1 uses the Compensatory Reserve Index to identify internal bleeding up to 30 minutes before traditional vital signs deteriorate — giving clinicians a critical intervention window.

THE COMPENSATORY RESERVE INDEX

Traditional vital signs like heart rate and blood pressure remain stable until 30-40% of blood volume is lost. CRI detects physiological compensation in real-time, revealing hemorrhage while intervention is still possible.

How CRI Works

The Science Behind Early Detection

CRI analyzes photoplethysmography waveforms to measure your body's compensatory reserve — revealing blood loss before vital signs change.

Traditional Vital Signs
  • Remain stable during compensated shock
  • Change only after 30-40% blood loss
  • Limited intervention window
  • Reactive treatment approach
CRI Monitoring
  • Detects physiological compensation early
  • Alerts 30+ minutes before vitals change
  • Critical intervention window
  • Proactive treatment decisions
