Gastric mucosal PCO2 tonometry is a physiologically sound monitoring technique, though methodological controversies remain regarding the best measurement medium and the need for acid suppression.
Gastric mucosal PCO2 tonometry is a physiologically sound adjunctive monitoring technique for regional perfusion, though methodological challenges remain regarding the optimal measurement medium.
Tonometry of gastric mucosal partial carbon dioxide tension (PCO2) has been forwarded as a clinically applicable tool to monitor regional perfusion adequacy during circulatory failure. The technique is still not used widely, partly because of methodological problems. Current measurement principles are reviewed, with help of the report on PCO2 measurements in gastric juice and tonometer in this issue.

AB Johan Groeneveld (2000) conducted an editorial in Circulatory failure and mucosal hypoperfusion. Gastric mucosal PCO2 tonometry was evaluated. Gastric mucosal PCO2 tonometry is a physiologically sound monitoring technique, though methodological controversies remain regarding the best measurement medium and the need for acid suppression.
