What are the vital signs?

Vital signs? (English: vital signs), or vital signs, are a set of four to six most important representations of basic physiological functions (maintaining life). These measurements are used to assess an individual's health, provide clues to potential diseases, and show the progress of rehabilitation. Everyone's normal vital signs? This range varies with age, weight, gender and overall health.

There are four main signs: body temperature, blood pressure, heart rhythm and respiratory rate, which are usually abbreviated as BT, BP, HR, RR and RR. However, according to the clinical environment, vital signs? May contain other measurement results, called "the fifth vital sign?" Or "the sixth vital sign?" . Vital signs? LOINC records follow the internationally recognized standard coding system.

Vital signs are indications for judging the severity and danger of patients. There are mainly changes in heart rate, pulse, blood pressure, respiration, pain, blood oxygen, pupil and corneal reflex. Under normal conditions, the pulse rate is 60- 100 beats/min (generally 70-80 beats/min).

When you are careful of cardiac insufficiency, shock, high fever, severe anemia and pain, thyroid crisis, myocarditis and atropine poisoning, your heart rate and pulse rate will increase significantly.

When increased intracranial pressure has complete atrioventricular block, the pulse slows down. Generally speaking, the heart rate is consistent with the pulse, but in arrhythmia such as atrial fibrillation and frequent premature beats, the pulse will be smaller than the heart rate, which is called short pulse.
