We recorded discharge frequencies of 32 intrapulmonary chemoreceptors (IPC) during caudocranial and craniocaudal ventilation in the perfused duck lung. Blood gases, ventilatory gas flow, inspired Pco2 and Po2' and expired Pco2 measured simultaneously were used to predict regional CO 2 and 02 gradien
