What is the purpose of monitoring a patient in shock? What kind of monitoring should be done?

Through monitoring, not only can further determine the diagnosis, but also can better judge the condition and guide the treatment. Usually the following monitoring:

(1) general monitoring: ① mental state: can reflect the perfusion of brain tissue; ② limb temperature, color: reflecting the perfusion of the body surface; ③ blood pressure: should be measured regularly and compared with the cuff method of measuring blood pressure is not permitted in shock, should be carried out when necessary radial artery puncture manometry; ④ pulse: the pulse is often fine before the drop in blood pressure, the pulse is clear, warmth of the hands and feet indicates that the shock is better; ⑤ urine volume: can be used to determine the diagnosis and better judgment and guide the treatment. The clear pulse and warmth of the hands and feet indicate that the shock is improving. ⑤ Urine volume: it can reflect the blood perfusion of the kidneys, and the observation of the hourly urine volume can help to understand the blood volume and renal function.

(2) Special monitoring: ①Central venous pressure; ②Pulmonary artery wedge pressure; ③Cardiac output and cardiac index; ④Arterial blood gas analysis; ⑤Arterial blood lactate measurement; ⑥Laboratory tests for DIC, etc.
