Key Points

To evaluate the feasibility and efficacy of using a carbon dioxide and oxygen gas mixture to enhance breathing effort during barometric whole-body plethysmography in cats.
Conducted barometric whole-body plethysmography to evaluate pulmonary function parameters.
Administered a combined carbon dioxide and oxygen gas mixture to stimulate ventilation in both healthy cats and cats with feline lower airway disease.
Exposure to the carbon dioxide and oxygen gas mixture stimulated respiratory drive, producing a short-term enhancement in breathing effort.
The intervention provided an effective and practical protocol for assessing dynamic lung mechanics in feline clinical settings.

Implication

Experimental study demonstrates enhanced breathing effort from carbon dioxide-oxygen mixtures in cats, indicating a practical option for clinical pulmonary testing.

Abstract

This approach provides a practical option for short-term breathing effort enhancement in cats for clinical settings.
