Ventilatory responses to carbon dioxide and hypoxia during acupuncture anesthesia in rabbits

Ventilatory responses to CO2 or hypoxia were examined in rabbits during acupuncture anesthesia and compared with responses during pentobarbital anesthesia. The responses during pentobarbital anesthesia were significantly less than those during acupuncture anesthesia. The results showed that acupuncture analgesia was effective during performance of these experiments.
