ARDS 10 Questions with Correct Answers

ARDS 10 Questions with Correct Answers


Question 1:
What is ARDS? (Milder form is acute lung injury)
Answer:
Inflammatory triggers initiate the release of cellular and chemical mediators causing injury to
the alveolar capillary membrane in addition to other structural damage to the lungs. Sever
ventilation-perfusion mismatch occurs. Aveoli collapse bc of the inflammatory infiltrate, blood
fluid, and surfactant dysfunction.



Question 2:
what causes ARDS?
Answer:
Direct injury- pulmonary contusion, pneumonia, near-drowning, aspiration, smoke inhalation.



Question 3:
Indirect- outside the lung, #1SEPSIS, BURNS.
Answer:
Indirect- outside the lung, #1SEPSIS, BURNS.



Question 4:
what diagnostic test is used to confirm ARDS?
Answer:
Chest xray-bilateral infiltrates on it.



Question 5:
ARDS is characterized by
Answer:
sudden and progressive pulmonary edema, increasing bilateral infiltrates on chest x-ray,
hypoxemia, reduced lung compliance (rigid, stiff lungs).

, Question 6:
Management for ARDS



Answer:
usually require ET and mechanical ventilation with a low tidal volume and higher than normal
airway pressure (PEEP)*.



Question 7:
What does PEEP do?
Answer:
positive end expiratory pressure keeps alveoli open improving oxygenation.



Question 8:
Medications for ARDS
Answer:
-cortisone therapy (used late).



Question 9:
-diuretics to reduce edema.
-vasodilator nitric oxide help ventilation perfusion mismatch.
-sedatives
-analgesics
Answer:
-vasodilator nitric oxide help ventilation perfusion mismatch.



Question 10:
