Body temperature, pulse, respiration, and blood pressure are among the four major vital signs of the human body. The normal value of respiration is about 16-22 beats/minute. Under normal circumstances, the number of pulse beats is equal to the number of heart beats, and its value is about 60-100 beats/minute. Blood pressure is systolic and diastolic, where the systolic value fluctuates in the range of 90-120 mmHg and diastolic in the range of 60-80 mmHg. Axillary temperature has a value of about 36.3-37.2°C. The younger the relative age, the faster the respiratory rate and pulse rate. Among them, the pulse rate of newborns can be up to 130-150 beats/min, children about 110-120 beats/min, and the respiratory rate of young children is about 30-40 beats/min. It is important to pay attention to the close observation of the patient’s vital signs during the development of the disease.
