the cessation of all physical and chemical processes that invariably occurs in all living organisms. Even in humans there is at present no standardized diagnosis of clinical death. The existing procedure, and the one recommended for use in animals, is to declare the animal dead when brain death has occurred. Brain death has occurred when the animal is in a deep irreversible coma. The criteria on which a diagnosis of brain death can be made are: (1) absolute unresponsiveness to externally applied stimuli; (2) cessation of movement and breathing, including no spontaneous breathing for 3 minutes after an artificial respirator has been turned off; and (3) complete absence of cephalic reflexes. The pupils of the eyes must be dilated and unresponsive to direct light.
