Gastrointestinal tonometry is a minimally-invasive method of assessing splanchnic perfusion. The measurement of regional-CO2 (PrCO2) and calculation of intra-mucosal pH (pHi) using the gastro-intestinal tonometer has been shown to be predictive of outcome in critically ill patients. Furthermore, the use of tonometrically derived data as therapeutic indices have been associated with improved outcome. The original balloon-saline method of tonometry was laborious, cumbersome and prone to systematic errors. The Tonocap® (Tonometries Division Instrumentarium Corp., Datex, Finland) is an automated on-line air based sy…
