I know a lot have questions as to what the results from OFA mean when you do the Trachea Study. When you do submit your application, you will receive a copy back with the results checked, and a number next to it. It has nothing to do with the size of a trach tube or anything else. Below is Dr. Kellers explanation.
>>>>>>
The number is a ratio of the inside diameter of the trachea at the thoracic inlet divided by the width of the proximal 3rd rib. The literature reports that a ratio of 2 or greater is normal. The BCA is trying to determine if this is accurate for the Bulldog and also to document the prevalence of hyoplastic tracheas.
Thank you.
