Normal vital signs are a key indicator of overall health. They represent the body's basic functions and can vary slightly depending on factors like age, sex, and physical condition. However, generally accepted ranges for adults include:
Key Vital Signs and Normal Ranges for Adults
- Blood Pressure: Between 90/60 mmHg and 120/80 mmHg. Readings outside this range may indicate hypertension (high blood pressure) or hypotension (low blood pressure). [Source: Mount Sinai, MedlinePlus, MyHealth Alberta]
- Pulse (Heart Rate): 60 to 100 beats per minute. A rate above 100 (tachycardia) or below 60 (bradycardia) can point to various health issues. [Source: Cleveland Clinic, Mount Sinai, MedlinePlus, StatPearls]
- Respiration Rate (Breathing): 12 to 18 breaths per minute. Abnormal breathing rates can signal respiratory problems. [Source: Cleveland Clinic, Mount Sinai, MedlinePlus]
- Temperature: 97.8°F to 99.1°F (36.5°C to 37.3°C); average 98.6°F (37°C). Fever (elevated temperature) or hypothermia (low temperature) indicate potential illness. [Source: Mount Sinai]
Important Note: These ranges are general guidelines. Individual variations are common. It's crucial to consult a healthcare professional for personalized assessments and interpretations of vital signs. Furthermore, the reliability of vital signs as indicators of health can vary, particularly in geriatric patients.

It's also important to remember that children and adolescents will have different normal ranges for their vital signs. These ranges change with age and growth. [Source: Iowa Head and Neck Protocols, Medscape]
