Answer

The most common causes of infiltrates in ventilated patients with fever and/or leukocytosis include the following conditions:

  • Pulmonary embolus or infarction
  • Pulmonary drug reactions
  • Collagen vascular diseases
  • Lung hemorrhage
  • Bronchiolitis obliterans-organizing pneumonia (BOOP)
  • Collagen-vascular diseases (eg, systemic lupus erythematosus [SLE])
  • Interstitial lung disease
  • Bronchogenic carcinomas
  • Metastatic carcinomas

ARDS is usually readily diagnosable based on the appearance of small lung volumes due to microatelectatic changes on the chest radiograph and the progressive and severe hypoxemia. Little or no fever accompanies ARDS, unless it is due to acute pancreatitis.
