- Defined as temperature ≥38°C (100.4°F).
- Peripheral temperature is not clinically accurate and central measurements are the preferred means of determining fever.
DDx by Heart Rate
Every 0.55°C increase in temperature should → increase HR by ~10BPM
- If patient has relative bradycardia, consider:
- If patient has frank bradycardia, consider:
