A high pressure of 70 mmHg and a low pressure of 40 mmHg is usually very serious and has entered the shock stage. High pressure 70mmHg belongs to severe hypotension, at this time the patient’s state of consciousness will not be very good, the appearance of this degree of blood pressure, often suggests that the patient’s heart disease has entered the end stage, there is severe heart failure, severe respiratory failure or severe malnutrition, the blood pressure will reach this degree. A high pressure below 90 mmHg is considered hypotension, and as the blood pressure decreases, the high pressure also gradually decreases, and the greater the decrease in high pressure, the more serious the shock state is, and the more serious the patient’s condition is, and the risk of death is very high. At this time, it is necessary to urgently apply intravenous antihypertensive drugs, you can choose to apply intravenous dopamine or dopamine combined with norepinephrine together with antihypertensive. In another case, a patient with a high pressure of 70 mmHg and a low pressure of 40 mmHg, but conscious and moving freely, with normal urination, may also be in a hypotensive state, partly related to genetics.
