The drop in blood pressure cannot be used as an indicator to determine the occurrence of shock. The indicators of the occurrence of shock should not only depend on the fall of blood pressure, but also observe other indicators, such as persistent hypotension, systolic blood pressure dropping below 90 mmHg for more than half an hour, or dropping 40 mmHg of the original blood pressure, accompanied by a state of tissue hypoperfusion. If the patient appears to have wet and cold skin, pale skin and cyanosis of the skin, urine volume is significantly reduced, the volume of urine per hour is less than 20ml, at the same time, the patient will appear impaired consciousness, at this time, blood gas analysis, blood gas analysis shows that the lactic acid is more than 2mmol/L, at the same time to determine the type of shock, at this time, the patient can be initially diagnosed to have shock. Once the diagnosis of shock is made, active treatment should be given, and the patient should be given rehydration therapy plus vasoactive drugs to correct the shock and treat the primary disease.
