Continuous positive airway pressure therapy for aspiration pneumonia in a dog.
A 14-year-old mixed-breed dog aspirated a large amount of liquid barium sulfate. Calculation of the alveolar arterial oxygen tension difference (34 mm of Hg; normal, less than 7.5 mm of Hg) from the alveolar gas equation and the arterial blood gas analysis indicated impaired pulmonary gas exchange. The dog was treated for 5 days with continuous positive airway pressure and supplemental oxygen administered by a simple apparatus connected to a tracheostomy tube. Continuous positive airway pressure was believed to improve gas exchange and to increase pulmonary compliance by decreasing alveolar collapse in this dog.
