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
