Question

Why does the ACLS protocol recommend epinephrine?

1) Increases muscular blood flow
2) Dilates the broncHIOles
3) Enhances myocardial contractility
4) Raises the systolic blood pressure

Answer 1

Epinephrine is recommended in the ACLS protocol to enhance myocardial contractility, raise systolic blood pressure, increase muscular blood flow, and dilate bronchioles.

Step-by-step explanation:

Epinephrine, also known as adrenaline, is recommended in the ACLS (Advanced Cardiac Life Support) protocol for a few reasons:

1. Enhances myocardial contractility: Epinephrine increases the force of the heart's contractions, allowing it to pump blood more effectively.
2. Raises the systolic blood pressure: By constricting blood vessels, epinephrine increases vascular resistance and helps raise blood pressure.
3. Increases muscular blood flow: Epinephrine dilates the blood vessels in skeletal muscles, improving blood flow and oxygen delivery to those muscles.
4. Dilates the bronchioles: Epinephrine acts as a bronchodilator, opening up the airways and increasing air volume in the lungs.
