Questions and Answers
  • 1. 

    Acts as a Vasodilator improving the blood flow to ventilated Alveoli. Reducing Intrapulmonary Shunting

    • A.

      Nitric Oxide

    • B.

      Nitrous Oxide

    • C.

      Oxygen

    • D.

      Helium

    Correct Answer
    A. Nitric Oxide
    Explanation
    Nitric oxide acts as a vasodilator, meaning it relaxes and widens blood vessels. This helps to improve blood flow to the ventilated alveoli, which are tiny air sacs in the lungs where gas exchange takes place. By improving blood flow to these alveoli, nitric oxide reduces intrapulmonary shunting, which is the mixing of oxygenated and deoxygenated blood in the lungs. This ultimately helps to optimize oxygenation and improve respiratory function.
