Intelligent analysis
Deterministic rules compare simulated readings with provisional demo reference ranges. The output is an attention level, not a diagnosis, and has no clinical validation.
Current assessment
Attention level
NOMINAL
All simulated readings are within the demo reference ranges and the sensors look reliable.
Levels: NOMINAL → ADVISORY (be aware) → CAUTION (check / follow checklist) → WARNING (request support). Sensor issues are shown in violet so they are never confused with a change in the body.
Can the readings be trusted?
Data reliability
High
93%
- HR94%
- SpO₂93%
- TEMP96%
- All sensors report good signal quality
Reliability describes data quality, not certainty about the crew member's health.
Explained in plain language
Findings (0)
No findings — all simulated readings are within the demo reference ranges and the sensors look reliable.
Thresholds: PROVISIONAL
Deterministic rules
Range check with persistence
Reports a deviation after 3 consecutive readings outside the demo reference range; clears after 3 consecutive readings back inside.
Dropout detection
Counts missing readings in the last 10 samples.
Plausibility limits
Flags values a working sensor should never report.
Rate-of-change check
Flags jumps between consecutive readings larger than the configured maximum step.
Signal quality
Flags mean signal quality below 60 % (poor below 40 %).
Frozen value
Flags a heart-rate value that stays exactly identical for 2 minutes.
Cross-check
An out-of-range value coming from a suspect sensor is reported as inconsistent and requires crew confirmation instead of being treated as a vital-sign change.
