ARDS NCLEX Review

What is ARDS (acute respiratory distress syndrome)? It’s a type of respiratory failure that occurs when the
capillary membrane that surrounds the alveoli sac becomes damaged, which causes fluid to leak into the
alveoli sac.

Result? Impaired gas exchange! Gas exchange doesn’t occur properly due to many reasons, such as: fluid in
the alveoli sac, collapsed alveoli sacs, and a decrease in lung compliance (hence the lungs are becoming
less elastic….”stiff”).

This will lead to oxygen not being able to cross the alveolar capillary membrane to go back in the blood to
oxygenate it, which will result in hypoxemia. In turn, the organs of the body will suffer due to this and death
can occur if treatment does not happen. In majority cases of ARDS, the patient will need respiratory
assistance via a ventilator with PEEP (discussed in detail below).

Quick Facts about Acute Respiratory Distress Syndrome (ARDS)

• It has a fast onset!
• It tends to occur in people who are already sick (hospitalized) and develops as a complication. For
example, a patient who has experienced severe burns is at risk for ARDS due to the systemic
inflammation present in the body.
• ARDS has a high mortality rate!
What can cause the capillary membrane to become more permeable and leak fluid? Usually events that lead to
major systemic inflammation in the body, which can be indirectly damage the capillary membrane or directly
damage the capillary membrane.

Indirect vs. Direct Injury to the Capillary Membrane

Indirect (source isn’t the lungs): the capillary membrane is INDIRECTLY damaged. There is a systemic
inflammatory response system (SIRS) by the immune system.

Common Causes:

• *Sepsis (most common and there is a very poor prognosis if the patient has a gram-negative bacteria)


: 패혈증 (가장 흔하며 환자에게 그람 음성균이있는 경우 예후가 매우 좋지 않음)

• Burns
• Blood transfusion (multiple)
• Inflammation of the pancreas (pancreatitis)
• Drug overdose
Direct (source is the lungs)….capillary membrane is DIRECTLY damaged

• Pneumonia
• Aspiration
• Inhaling a toxic substance
• Significant drowning event
• Embolism
