“…It is uncertain why lung collapse was more frequent in larger dogs. It is known that intermittent positive pressure ventilation to minimize lung collapse is required more frequently in large dogs than small dogs or cats, and this may reflect the larger gravitational gradient that occurs within the lung of larger patients, as observed in anesthetized horses …”

In computed tomographic (CT) images of humans, decreased lung attenuation, bronchial dilation, and/or thickening, air trapping, cysts, and thickened interlobular septa have been associated with increasing age. To determine if there are differences in the CT appearance of the lungs of young and old dogs that could affect interpretation of diagnostic studies, pulmonary CT images of dogs with conditions unrelated to the thorax were reviewed retrospectively in a case-control study. Computed tomography studies of 42 young dogs (range 0.3-4.8 years) and 47 old dogs (range 9-15.1 years) were jumbled and reviewed by an observer blinded to dog age. Computed tomography was performed under sedation in 62 (70%) dogs and under general anesthesia in 27 (30%). Heterotopic bone was more prevalent (62% vs. 14%) in old dogs. Lung collapse was significantly associated with old age, greater body weight, and anesthesia. There were no significant differences in median lung attenuation or occurrence of ground glass pattern, cysts, bronchial thickening, bronchial dilation, or degree of tracheal calcification. No examples of reticular pattern, emphysema, pleural thickening, or septal thickening were observed in any dog. Despite previous studies describing age-related changes in the radiographic appearance of the lungs of old dogs, it appears that there are minimal observable differences in CT images. Old dogs are more likely to have visible foci of heterotopic bone and may be more prone to lung lobe collapse than young dogs, but neither of these differences should contribute to misdiagnosis of pulmonary disease.

“…However, this imaging technique is impractical in horses. New technologies, such as electrical impedance tomography, allow the evaluation of ventilation of the lungs in adult horses and may be of use in gaining more information on the effect of CPAP on equine lungs (Moens et al 2014).…”

“…A secondary consideration is our ability or inability to determine (beyond an increase in PaO 2 ) if the methods truly produce beneficial effects. A recent case report introduces noninvasive methods of assessing pulmonary status that may be of benefit in marking this assessment . The application of PEEP, CPAP or recruitment manoeuvres results in higher mean airway pressure and thus higher mean intrathoracic pressures that lead to decreases in P and Q T .…”

Horses are the most difficult of the common companion animals to anaesthetise. Hypoxaemia or inadequate oxygen delivery to peripheral tissues during anaesthesia would seem a potential cause of increased mortality, but no direct link has been established. A number of methods of increasing oxygenation and oxygen delivery have been reported, with varying results and potential applicability. The purpose of this article is to review the literature with regard to oxygenation, oxygen delivery and methods to improve each and to make recommendations for clinical application.
