Vital Signs Monitoring

What Is Vital Signs Monitoring?

Vital signs monitoring is the continuous prehospital measurement of key physiological parameters — Heart Rate, Blood Pressure, Respiratory Rate, SpO2, ETCO2, Temperature, and ECG rhythm — to evaluate patient stability and treatment response.

Why Vital Signs Monitoring Matters on the Fireground

Single vital sign measurements are just a snapshot; monitoring trends over time reveals subtle physiological decline (such as widening pulse pressure or rising shock index) long before catastrophic collapse.

Relevant NFPA Standards

• NREMT Standards: National Registry of Emergency Medical Technicians Practice Standards
• NFPA 455: Standard for Emergency Medical Services (EMS)

Field Procedures & Tactical Steps

1. Obtain full baseline set of vital signs (HR, BP, RR, SpO2, ETCO2, Temp, GCS).
2. Attach automated monitor (NIBP cuff, 4-lead ECG, pulse oximeter).
3. Evaluate numerical values against age-appropriate normal ranges.
4. Re-measure vitals every 5 minutes for critical calls or 15 minutes for non-critical calls.
5. Document vital sign trends and report significant changes to receiving hospital staff.

Common Context & Application

Performed on every prehospital EMS transport, critical care transfer, and rehab sector firefighter evaluation.
