This is a video of a normal horse breathing.
This is a video of a horse with heaves breathing. Notice that the horse is standing still but he is having trouble breathing. His head and neck are extended. His nostrils are flaring and his chest is moving up and down in a jerky fashion. We can also get you a video of a normal horse breathing.
This video shows the endoscope being placed down the horse's airway. The controls are on the end that the vet holds. The vet can then move the tip that is in the horse and control where the camera points. The image is displayed on the video screen.
Endoscopy - Normal Horse
This is endoscopy is of a normal horse without airway breathing problems.
Endoscopy - Airway Problems
This is endoscopy of a horse with airway problems. A long scope with a camera attached is placed down the horse's trachea. At 14-16 seconds you can see mucus on the bottom middle of the airway. At 30 seconds the airway forks into the bronchi going to the two different sides of the lung. The division is rounded and thickened. The airway collapses when the horse breathes.
This video shows different levels of mucus accumulation in the airway of a horse.
The project described was supported by a Science Education Partnership Award (SEPA) from the Office of Research Infrastructure Programs (ORIP), a component of the National Institutes of Health (NIH).
