 [to-nom´ĕ-tre]
measurement of tension or pressure, e.g., intraocular pressure.
digital tonometry estimation of the degree of intraocular pressure by pressure exerted on the eyeball by the finger of the examiner.
gastric tonometry monitoring of the gastric intramucosal pH to obtain early indications of inadequate tissue oxygenation; the sensitive nature of the mucosa allows for monitoring of metabolic changes produced by hypoxia well in advance of the other more common indices of hypoxia.

gastric tonometry

Measurement of the partial pressure of carbon dioxide (Pco2) in the stomach of critically ill patients to determine how well the stomach and other internal organs are perfused with blood and oxygen. Poor gastric perfusion is found in more severe conditions, i.e., those that carry an increased risk of death.
