- Vital sign changes (Δ in readings)
Example:
- ΔBP = change in blood pressure
- ΔHR = change in heart rate
Emergency medicine:
A triangle symbol may indicate:
- Warning condition
- Priority patient status
- Critical change in health metrics
Doctors also use triangular models to understand body systems balance.
