1, blood pressure: including systolic pressure and diastolic pressure. Normal systolic blood pressure is 90- 140mmHg, and normal diastolic blood pressure is 60-90mmHg. If blood pressure continues to be higher than the normal range, symptoms of hypertension may occur.
2. Heart rate: The normal heart rate is between 60- 100 beats/min. Too fast or too slow heart rate is an abnormal situation, which needs attention and timely treatment.
3. Breathing: The normal breathing frequency is generally 12-20 times per minute. If you breathe too fast or too slowly, you need to be examined and treated.
4. Body temperature: Usually the normal body temperature is between 36.5 and 37.2℃. If the body temperature is too high or too low, it may mean that there are some problems in the body. In the comprehensive analysis, it is necessary to combine the data of these four aspects to evaluate the health status of patients. If one vital sign is obviously different from the normal value, or several vital signs are abnormal, it is necessary to further understand the patient's medical history and symptoms to determine whether diagnosis or treatment is needed.
