I have done that on a couple of exotics when darting for capture. In the old days we used Sucostrin which was a neurological paralytic drug that was commonly used for darting animals. Sometimes it would cause them to stop breathing and you had no choice if you didn't want to lose an expensive animal
After a couple of times doing that I got a dog
BVM ( some call it an Ambu-bag) from our vet. We also started carrying a portable medical oxygen bottle to facilitate getting them more O2.
Axis were notorious for doing that after darting. We always made the best effort possible because if I killed an animal while capturing the cost of the animal was on me sometimes.
