CMPP -- Acute Respiratory Distress Syndrome

Acute respiratory distress syndrome

non-cardiogenic pulmonary edema; secondary to an underlying disease process

sepsis

most common cause of ARDS?

profound hypoxia

patients with ARDS present with...

diffuse alveolar injury, fluid leakage into the alveolar lumen and severe hypoxia

inflammation increases permeability of the alveolar-capillary membrane and fluid leakage into the alveoli

in a patient with ARDs, the underling disease process causes...

bilateral pulmonary infiltrates in the setting of a normal heart size

what is normally seen on CXR for one with ARDS

pulmonary capillary wedge pressure

measuring ______ differentiates ARDs from CHF

hypoxia, acidosis, pulmonary artery vasoconstriction

the hypoxia caused by increased intra-alveolar fluid leads to _____ and ______, which leads to __________.

underlying disease --> membrane damage --> fluid leaks into the alveoli --> impairs gas exchange --> profound hypoxia
