What does stroke fast mean?

The FAST principle in the brain is designed to quickly identify stroke in order to gain first aid time for stroke. F stands for Face, which refers to whether there is a skewed mouth on one side of the face, or numbness or weakness in the face. A stands for Arm, which refers to whether there is weakness in the upper limbs, allowing the patient to lift both upper limbs. See if there is a difference in strength in one limb, unable to lift or grip. S stands for Speech, which refers to whether the patient has difficulty speaking and speech comprehension or pronunciation. T stands for Time, which aims to emphasize time, treatment time of stroke and thrombolytic time window. Within thrombolytic time window, if contraindications are excluded, thrombolytic therapy needs to be considered. Of course, thrombolytic therapy has certain risks, and it is necessary to fully inform the patient's family and seek the consent of the patient's family. In addition, active treatment of stroke is conducive to alleviating brain cell damage and is conducive to recovery and prognosis of the disease.
