Final answer:
The cord used in hypertensive patients is soaked with epinephrine, which is used to quickly raise blood pressure during an episode of hypotension. This emergency treatment involves vasoconstriction and should be administered under medical supervision.
Step-by-step explanation:
Epinephrine, also known as adrenaline, is a drug that can treat various conditions, including hypotension. Hypotension is a condition characterized by low blood pressure. Epinephrine can cause vasoconstriction, which narrows the blood vessels, and this increases blood pressure. In some cases, a hypertensive patient might experience a sudden drop in blood pressure, and an epinephrine-soaked cord can be used as an emergency treatment to quickly raise the blood pressure.
It is important to use such treatment under medical supervision, as improper use can lead to significant health risks. Keep in mind that diuretics are also used to treat hypertension and work by causing the body to expel excess sodium and water, which reduces blood volume and pressure. However, this is different from the immediate action of epinephrine in treating hypotension.
