Ok I get that they want to check for problems in their airways, but doesn't this seem dangerous without a safety harness? Especially that Thoroughbred running at top speed, if something happened and he tripped that wouldn't be pretty. What do you think?
They don't just test for breathing they test heart rate as well as oxygen levels. I have worked with a few on these devices and they do catch on pretty quick. I have also had the "Pleasure" of seeing how the oxygen chamber works with horses. And of course good ol swimming and aqua tred. I could only dream of having these devices to use when needed. More so the pool and the oxygen chamber.
This is a amazing procedure and does wonders for horses as well as people.
