Protocol for Pre-Sale Videoendoscopic Examination of the Upper Airway at Public Auction

  • Equipment must be capable of producing a digital video image of excellent quality.
  • Horse must be identified appropriately, and that identification must be in digital format with character generation on the screen, and/or video for the catalog page, followed by unbroken video of the face prior to introduction of the scope into the nares (right or left) and up to the larynx. This is the single stream video with no editing. 
  • The veterinarian performing the video endoscopy may upload the video at the same time radiographs are uploaded to the OBS repository. Veterinarians or the consignor may also submit each upper airway video on an individual flash drive or CD. Upper airway videos should be stored in a file separate from the radiographs. 
  • Standard technique must include maximal abduction of arytenoids induced by swallowing (multiple times) and nasal occlusion. The duration of the video must be sufficient to identify all laryngeal and pharyngeal structures as well as observing their maximal function within the context of a resting exam. 
  • The interval between the pre-sale video endoscopic exam and the selling session will not exceed (10) days.
