If the patient’s low pressure, i.e. diastolic blood pressure, is 40 mmHg, this condition is considered hypotension and the first thing to do is to repeat the measurement to rule out whether it is due to a measurement error. It is recommended that the patient can further find out if this is due to an overdose of antihypertensive medication or the result of taking some medication that affects blood pressure. If this is the cause, the medication that affects blood pressure should be stopped and the blood pressure will gradually recover. However, if the current systolic blood pressure is also relatively low, it is recommended that dopamine, dobutamine treatment can be ordered quietly to raise blood pressure, if the systolic blood pressure is mildly reduced, the patient can also be advised to take oral raw pulse drink or quietly ordered ginseng injection drugs to raise blood pressure. The diet of high quality protein, currently mainly egg whites, silkworm pupae, sea cucumber, red beef and mutton, can help to raise blood pressure to a certain extent.
