Pulmonary function testing in horses.

Abstract: Pulmonary function tests in horses are in the early stages of development and there will be a limit in the range of tests available since those requiring patient cooperation cannot be conducted in animals. Some tests such as blood gas analysis, A-aDo2 and delta Ppl measurements could presently be used to a greater extent under field conditions. Others that require expensive equipment and considerable technical assistance will be limited to the larger referral type veterinary clinics until the time is reached when there is adequate information to select those procedures that give a reasonable cost to benefit ratio to make their use more widespread.

This research article discusses the current state and future potential of pulmonary function testing in horses, noting that it is in early development stages and has some limitations, including the need for costly equipment and technical help, and the inability for some tests to be done due to lack of patient cooperation.

Pulmonary Function Tests in Horses

  • The article begins by acknowledging that pulmonary function testing in horses is still in its infancy, but that these tests can potentially contribute a lot to understanding and improving equine health.
  • The authors note that not all the tests that are commonly used in humans can be used in horses since some require the cooperation of the patient, which is not feasible in animals. Examples of these include spirometry or lung volume tests which require the patient to breathe in and out forcefully and deeply.

Potential Use Under Field Conditions

  • The article points out that currently there are some tests that are feasible and could be used more extensively under field conditions, providing valuable insights into equine pulmonary health.
  • These more feasible tests include blood gas analysis, Arterial- alveolar oxygen difference (A-aDo2), and changes in pleural pressure (∆Ppl) measurements. The blood gas analysis measures the amount of oxygen and carbon dioxide in the blood and could be useful in evaluating the respiratory functions in horses. A-aDo2 is the difference between the oxygen pressure in the alveoli and in the arteries. This test is useful in diagnosing diffusion impairments. Delta Ppl is a measure of the changes in pleural pressure and can help in assessing the mechanical properties of the chest wall and lungs.

Limitations and Cost Considerations

  • The authors state that there are potential tests that require expensive equipment and considerable technical assistance.
  • These would likely only be feasible in larger, referral-based veterinary clinics with greater financial resources and specialized staff. Until there is more definitive information on which procedures provide a beneficial cost-to-benefit ratio, the widespread usage of such tests may not grow significantly.
  • This connects back to the early stage of development of pulmonary function tests in horses – as more research and understanding emerges, it will become clearer which tests are most effective and how they can be made more accessible and cost-effective.
