Blood Pressure tracking is very useful for the patient and for the doctor in deciding the line of treatment. Doctors routinely monitor four main Vital signs. Vital signs are useful in detecting and monitoring the medical problems. The normal body temperature of a person varies depending on gender, recent activity, food and fluid consumption, time of day, and, in women, the stage of the menstrual cycle. Normal body temperature can range from 97.8 degrees Fahrenheit to 99 degrees Fahrenheit for a healthy adult. The pulse rate is a measurement of the heart rate, or the number of times the heart beats per minute. The normal pulse for healthy adults ranges from 60 to 100 beats per minute. The respiration rate is the number of breaths a person takes per minute. Normal respiration rates for an adult person at rest range from 12 to 16 breaths per minute. Blood pressure is the blood force pushing against the artery walls during contraction and relaxation of the heart. Normal blood pressure is systolic of less than 120 and diastolic of less than 80 (120/80).
