When the blood pressure rises above 200/120mmHg, the first step is to take sedative drugs (such as Valium and Nitroxazepam, etc.), let the patient lie quietly in bed, and if necessary, take cardiac painkillers (5mg), to monitor the blood pressure and send the patient to the hospital for medical treatment in a timely manner.

Patients who have already had a cerebral hemorrhage will have their blood pressure rise again, so they should be sent to the hospital as soon as possible to control their blood pressure at about 150/85mmHg to prevent the recurrence of cerebral hemorrhage.

The blood pressure of patients with cerebral thrombosis should not be lowered too much when the blood pressure increases, and should be kept around 150/100mmHg first, so as to prevent the blood pressure from being lowered too much and the blood flow from being reduced too much, which will make the condition recur or aggravate.

Coronary artery disease patients with a momentary increase in blood pressure should not be lowered too low, it is best to maintain at 130-140/80-85mmHg, although the blood pressure is too high will increase as well as the burden on the myocardial oxygen consumption increases, but the blood pressure is too low can also affect the coronary perfusion exacerbated myocardial ischemia. After the above treatment, the condition will be improved, and the amount of daily antihypertensive drugs will be appropriately reduced until the blood pressure is maintained at a stable level. If the blood pressure control is still not satisfactory, you should go to the hospital for further diagnosis and examination.
