Stage 3 anaesthesia is divided into four planes. o Plane 1: "light" anaesthesia - the animal still has blink and swallowing reflexes, and regular respiration. o Plane 2: "surgical" anaesthesia - the animal has lost blink reflexes, pupils become fixed and respiration is regular. o Plane 3: "deep" anaesthesia - the ...
