Hyperbaric air therapy (HBA) is a treatment in which an animal is exposed to air pressurized to about 1.3 atmosphere absolute (ATA). Although HBA has already been administered to humans in medical applications, it has not been reported in clinical veterinary medicine. Therefore, we aimed to determine a safe protocol for dogs. To elucidate oxygen dynamics during HBA, we measured partial pressure of arterial oxygen, oxygen saturation of tissue, and partial pressure of transcutaneous oxygen in dogs. HBA could be performed safely with a protocol of pressurizing speed up to 0.1 ATA/min, maximum chamber pressure of up to 1.3 ATA, and pressure duration of around 45 min per treatment. Under these conditions, tissue was adequately oxygenated during and after treatment.
