What happens to the anaesthetic concentration of an animal when it is hyperventilating and how do you correct the situation?
A hyperventilation on the Stephens machine occurs when an animal is too lightly anesthetised. The anaesthetic concentration is normally too LOW. The situation can be corrected by turning up the vapouriser to a higher setting. For a few breathers then returning to a lower setting usually the 3/8 or 1/4 setting.
