Treatment is dependent on the underlying cause of the oxygen deficiency. Oxygen will be given to support your dog's heart and lungs (cardiovascular system) using a face mask placed securely around the muzzle to deliver the oxygen. It is important to keep in mind, however, that this treatment is not always successful.
If the problem is low cardiac output, intravenous (IV) medications to strengthen muscle action will be prescribed. In case of cardiac failure, diuretics and oxygen will be administered, as well as medications to strengthen muscle action.
If there is hemorrhaging, injury, or shock from infection, hospitalization will be required to get an IV inserted and fluids flowing into the veins. This will also allow the oxygen to reach appropriate levels.
Hypoxemia is a life-threatening condition. Therefore, observe your dog's behavior carefully following the treatment. Symptoms to watch for include a decreased ability to breathe, as well any paleness of the tissues, which would be indicative of a lack of oxygen diffusion to the tissues. Frequent follow-up visits to the veterinarian will be needed to track arterial blood gas levels.
