The definitive treatment is to treat the primary cause, discontinue inhalation anesthesia, or provide adequate ventilation during anesthesia. Your veterinarian will begin by providing adequate ventilation into the air cells of the lungs. If your cat is anesthetized, your doctor will accomplish ventilation manually or mechanically with an anesthesia ventilator.
Non-anesthetized cats with severe pulmonary or central nervous system disease can be treated by mechanical ventilation with a critical care ventilator, but the cat may require heavy sedation for this treatment. Supplemental oxygen will be determined by the primary disease, since providing supplemental oxygen without providing ventilation generally will not correct hypercapnia.
Your doctor will assess the effectiveness of supportive (ventilation) and definitive treatment. This should result in a decrease in the respiratory effort. Arterial blood gas will be evaluated to determine improvement, and to assess the adequacy of your cat's ability to take in adequate amounts of free oxygen as needed.
