Plain-English summary
A group of 14 dogs with breathing problems underwent a procedure called a transoral tracheal wash (TOTW) to help clear their airways. After the wash, the dogs showed a decrease in lung compliance, which means their lungs were less able to expand properly, likely due to fluid in the airways. While this change was temporary and didn't lead to long-lasting issues, it highlights the need for careful monitoring during this procedure. Overall, the TOTW can be beneficial for dogs with respiratory diseases, but pet owners should be aware of potential short-term effects on breathing mechanics.

Abstract
The purpose of this study was to determine the impact of a transoral tracheal wash (TOTW) on respiratory mechanics in dogs and to describe the use of a critical care ventilator (CCV) to determine respiratory mechanics. Fourteen client-owned dogs with respiratory diseases were enrolled. Respiratory mechanics, including static compliance (C) and static resistance (R), were determined before and after TOTW. Pre- and post-wash results were compared, with a-value of < 0.05 considered significant. The mean ± standard deviation (SD) value of Cpre-TOTW was 1.59 ± 0.94 mL/cmHO/kg while the mean ± SD of Cpost-TOTW was 1.29 ± 0.71 mL/cmHO/kg (= 0.045). The median Rwas not significantly different pre- and post-wash. The transoral tracheal wash altered respiratory mechanics, as observed by a reduction in C, presumably due to airway flooding and collapse. While no long-lasting effects were noted in these clinical patients, this effect should be considered when performing TOTW on dogs with respiratory diseases. Respiratory mechanics testing using a CCV was feasible and may be a useful clinical testing approach.
