The blood pressure adjusts to the heart's needs and these depend on what the person is doing. So it naturally goes up and down all the time.
The blood pressure of the patient in the emergency department is: 82/40. 82/40 is not a normal blood pressure. Optimum blood pressure for the patient should be 120/80. So, I should give the patient some medication to treat his low blood pressure. I could use the drug midodrine (Orvaten) , for example, to raise my patient's blood pressure. This drug restricts the ability of the blood vessels to expand and by doing so it raises the blood pressure.
