First Set of Vital Signs: Baseline Assessment in Clinical Practice

When a patient presents for care, the initial (baseline) vital signs establish a reference point for monitoring clinical trajectory.

Core Components

Parameter	Normal Adult Range	Clinical Significance
Blood Pressure	90–120 / 60–80 mmHg	Perfusion pressure; hypotension/hypertension alerts
Heart Rate	60–100 bpm	Cardiac output surrogate; tachycardia/bradycardia flags
Respiratory Rate	12–20 breaths/min	Ventilation adequacy; early sepsis/COPD exacerbation sign
Temperature	36.5–37.5 °C (97.7–99.5 °F)	Infection, inflammation, thermoregulation failure
Oxygen Saturation (SpO₂)	>95% room air	Hypoxemia detection (often added as 5th vital)
Pain Score	0–10 scale	Subjective but essential for comfort/safety

Document time, method (manual vs. automated), patient position, and any anomalies. Trends matter more than single values.
