title: Tonometry to assess the adequacy of splanchnic oxygenation in the critically ill patient.
abstract: Tonometry, a relatively non-invasive technique for indirectly measuring the intramucosal pH (pHi) of the gastrointestinal tract, has recently been developed for use in critically ill patients. Reports in the literature suggest that the technique is of greatest benefit to patients at risk of developing reductions in splanchnic oxygenation (decreased O2 delivery) in whom early detection of the ischemic episode could possibly guide treatment. Tonometry, although still at a relatively early stage in its clinical development, could be of value for selected patient groups although further evaluation of the technique is necessary.
