Adult Respiratory Distress Syndrome (ARDS)
A sequela of several diseases in which the lungs fill with water, making gas exchange impossible
Etiology
Results from unknown cause.
Predisposing factors
Pneumonia
Near drowning or Reaction to drugs and inhaled gases
Allergic reactions (pulmonary)
Shock Infection
Diabetic ketoacidosis
Trauma
Burns
Pathophysiology
Increased permeability of alveolar-capillary membrane
penetration of protein and fluid from the IV compartment into the pulmonary
interstitial and alveoli
noncardiac pulmonary edema
Plasma protein inactivates surfactant
injury to the alveolar cells
surface tension
Increased pressure from excessive fluid and increased surface tension
Alveolar collapse
Stiffening of the lungs
Difficulty in inflation
Decreased lung compliance and increased work of breathing
Symptoms include:
Crackles and gurgles
Hypoxemia due to poor diffusion
Respiratory distress
X-ray result – mass consolidation
ABG Analysis: Respiratory acidosis
Nursing Interventions
Monitor fluid intake
Administer steroids as ordered - reduce inflammation
Assess for complication like pneumothorax
Institute PEEP as ordered
Provide care necessary for a mechanical ventilator
Protecting the airway from injury
Relieve anxiety
