 Today, here in the field, the focus is going to be on throat issues during exercise. It's a very common issue. Some studies found that the number one most common is lameness and number two is breathing issue in horses. And so today we're going to look at just the upper part of the respiratory system, so what we call the upper way, which is basically the throat. Now we have that camera system that is portable and going on the horse during exercise with the rider riding. So now it provides us all that information we need to look in real time and see exactly what's going on in that throat and then get the best treatment and the best fix for that. So it's called a dynamic endoscopy and endoscopy means inside and looking inside, endoscope for view and look inside. So that's exactly what we do. We have an endoscope, so it's a camera at the end of a kind of a semi flexible tube basically and the tube goes into the nose until we can see the throat. So that's the cell pad with the equipment so you can see those kind of backpacks here. So that's where we have the battery on one side and the power source for the light and then on the other side we have that antenna and we have that recorder. There is also here a pump and a small reservoir, a small bottle with distilled water and so that pump we can program it to basically push some water into the scope, into the camera and it will basically clean up the lens of the camera because the horses can have some mucous and so the way it works is we put first this saddle pad on the horse then the saddle and we can adjust the position of the pads back and forth up and down. The endoscope is attached to the horse and that's the tip with the camera so I can steer only one direction and if I turn the wheel down it will move the endoscope, bend the endoscope like that. We have some lights and we have the nozzle here to spread the water and so this is going to go into the horse head like this and it is going to look down like that at the throat and now we have to keep it in place like this. Good girl. We also have a screen so there is a small antenna and the device on the horse on the pad will send us the videos on the side of the track so from the side we can see what's going on. I usually use a screen to monitor the position, make sure I have a good quality recording but in all cases I'm going to take the USB key, the recording, put it in my laptop back in the office and then I'll review the videos in slow motion. The more the throat is open the better and any time you have some weakness, some collapse, some narrowing, you're decreasing the diameter for the air to go through and then it becomes more like a whistle so you want a throat as open as possible and unfortunately horses have trouble with their throat to keep it open with such a high speed so that's why we are quite busy doing those endoscopies. I hope that video today helped you to understand why we do those dynamic endoscopies and how we do them. I hope it can be helpful for you in the future if you have any breathing respiratory issues on your horses and I'll be very happy to answer any question you have now.
