Plain-English summary
A 5-year-old male mixed-breed dog was treated for a chronic pneumothorax, which is a condition where air collects in the chest cavity and can affect breathing. After the air was completely removed, the dog showed better oxygen levels, but surprisingly, its ability to breathe out worsened. This unusual response indicates that while removing the air pocket can help with oxygenation, it might also lead to complications by making it harder for the dog to ventilate properly. It's important for pet owners to be aware of this potential issue when their dog is treated for pneumothorax.

Abstract
OBJECTIVE: To describe an unusual response to evacuation of a chronic pneumothorax in a dog. CASE: Resolution of a pneumothorax is usually associated with lung expansion and a marked improvement in pulmonary function. In the case presented here, evacuation of a chronic pneumothorax improved oxygenation, but markedly impaired ventilation. CLINICAL RELEVANCE: This is a previously unreported complication associated with the treatment of pneumothorax in dogs. It suggests that in some cases of chronic pneumothorax, total evacuation of the pleural air pocket may improve oxygenation but ventilation deteriorates and increases PCO2, causing further complications.
