Body Temperature: The average body temperature is degrees Fahrenheit, but normal temperature for a healthy person can range between to degrees Fahrenheit or slightly higher. Remember, normal adult vital signs may vary according to age, gender, weight, exercise tolerance, and physical conditioning. The best way to get the most accurate guidelines for what's "normal" for yourself or your COPD patient is to consult your healthcare provider. Vital signs reflect essential body functions, including your heartbeat, breathing rate, temperature, and blood pressure. Your health care provider may watch, measure, or monitor your vital signs to check your level of physical functioning. Normal vital signs change with age, sex, weight, exercise capability, and overall health.
