1. Clear the objects around the patient, and do not forcibly restrain or move the patient to prevent injury to the patient's head and cervical spine.
2. Never force anything in the patient's mouth to be bitten by the patient to avoid blockage of the patient's airway.
3. Wait for the patient's convulsions to stop. If the patient's convulsions last for more than 5 minutes, more than 2 consecutive convulsions or has been injured during the convulsions, call 119 for help.
4. If the patient is not breathing normally, call 119 for help as soon as possible and perform cardiopulmonary resuscitation (CPR) first aid immediately.
