Vital signs are measurements of the body’s basic functions, taken to evaluate the general physical health of a person, track progress during treatment or offer information about possible disease states. The four main vital signs are blood pressure, body temperature, pulse (or heart rate) and respiration (breathing rate).
In Our Own Words
Vital signs are measurements that provide indications of general health and how well the body is functioning. The four main vital signs are blood pressure, body temperature, your pulse (or heart rate) and also breathing rate.
Measurements are then compared to what is within the normal range for healthy adults:
1. Body temperature. Normal can range from 97.8 to 99.1 degrees Fahrenheit or even slightly higher.
2. Blood pressure. At or less than 120/80 millimeters of mercury.
3. Pulse rate. For a healthy adult, 60 to 80 beats a minute is considered a normal range at rest. A too-rapid pulse might indicate problems such as a heart condition or emphysema.
4. Normal respiration rate is 12 to 20 breaths a minute, at rest. Certain conditions, including heart failure, lung disease and asthma, can make this vital sign abnormal.
