title: A simple method for the sampling of respiratory gas in conscious dogs.
abstract: A method is presented for the sampling of respiratory gas in conscious animals, using a catheter with the tip implanted in the roof of the nasal cavity and the other end exteriorized beyond the external protuberance of the occiput. The operation procedure is simple and serious postoperative complications have not been encountered. The method has been used extensively for the continuous measurement of Po2 and PCO2 in respiratory gas of conscious dogs.
