Algorithm 1 The main triage algorithm implemented in the Analysis and Inference Subsystem.

Input:   Measured values of RR, HR, SBP and SpO2.   Personalized reference and critical values of the vital signs for each soldier.   Typical reference values:     RRref: 9–20/min     HRref: 50–110/min     SBPref: 100–180 mmHg     SpO2ref: >= 94%   RRctitical, HRcritical, SBPcritical, SpO2Critical Output:   Triage Steps: 1. Read RR 2. if RR == RRref then 3. | triage <- (Green) 4. else if RR != RRctitical 5. | triage <- (Yellow) 6. else 7.  triage <- (Red) 8.
