When recovering from an anaesthetic dogs are left on oxygen for 5-10 minutes. Extubation should occur when the dog regains its ability to swallow, this can be indicated by their first cough. It is vital the cuff of the ET tube is allowed to deflate before the dog is extubated.
Cats differ from dogs as they need to be extubated BEFORE they regain the ability to swallow to prevent laryngeal spasm. Therefore it is important to play close attention to increased jaw tone and look for an ear twitch when the hair on the ears is gently stroked.
