An apparatus for multiple channel perfused gastrointestinal manometry particularly useful for animals and small children which avoids errors in pressure measurement due to air bubbles, particularly micro- bubbles in the channels. Achieved by the use of a carbon dioxide flush of the apparatus to displace the air bubbles in the manifold and manometry lines. The carbon dioxide is subsequently dissolved in the subsequent flow of manometric infusate.
