  • This led to important results about the role of the oceans in the regulation of the CO2 of the atmosphere and also set out the principles of tonometric measurement of dissolved gases which he later applied to physiological problems (1904).

  • In his recent tonometric studies Schoenberg noted that under manipulation the glaucomatous eye softened more slowly than the normal eye; and suggests this diminished drainage as an important evidence of glaucoma.

  • Perhaps we may reach that happy day when, especially with improved tonometric methods, increased skill in measuring the rate of filtration and better instruments for determining the light sense, we can anticipate the advent of glaucoma and get ahead of the ocular and visual deterioration which increased tension produces, by performing preventive operations which shall aid nature's filtration channels in the establishment of an artificial one.

  • Levy et al. 38 compared the effects of epinephrine with the combination of norepinephrine and dobutamine on gastric tonometric variables in 30 septic shock patients and found that while systemic hemodynamics were similar, pHi and gastric PCO2 gap were normalized within 6 hrs with norepinephrine and dobutamine while pHi decreased and gastric PCO2 gaps increased in epinephrine-treated patients.

  • Gastric mucosal PCO2 is influenced directly by systemic arterial PCO2, however, and so use of the gastric-arterial PCO2 difference has been proposed as the primary tonometric variable of interest, although even this measure is not a simple measure of gastric mucosal hypoxia. 21 Despite this complexity, gastric tonometry is a good predictor for the ultimate outcome of critically-ill patients. 22-25 Its utility to guide therapy in patients with sepsis and septic shock, however, has not been proven.
