Monitors, Bedside, Gastrointestinal Tissue, Carbon Dioxide
Definition : Bedside monitors designed for continuous evaluation and display of the partial pressure of carbon dioxide (PCO2) in the gastrointestinal tissue (PgCO2). These devices typically consist of an external monitoring instrument that displays periodically (e.g., every 10 minutes) the values of PgCO2 taken from samples automatically withdrawn from a nasogastric catheter that includes a gas-permeable balloon attached at its distal end, without retrieving the balloon from the gastrointestinal duct. The monitoring unit is frequently incorporated as a module of a physiologic monitor. Gastrointestinal tissue carbon dioxide monitors are used mainly to assess gastrointestinal perfusion in hemodynamically unstable, critically ill patients.
