BACKGROUND Saline gastric tonometry of carbon dioxide has been proposed as a means to assess the adequacy of splanchnic perfusion. However, this technique has several disadvantages, including the long time interval needed for gases to reach equilibrium in saline milieu. Thus the authors evaluated a system that uses a gas-filled instead of a saline-filled gastric balloon. METHODS In vitro, we simultaneously placed two tonometry catheters in an equilibration water bath maintained at a… CONTINUE READING
