Gastric tonometry is gaining acceptance rapidly as a noninvasive metho
d of monitoring tissue dysoxia in a key organ system that previously c
ould not be assessed easily. in addition to being noninvasive, gastric
tonometry also identifies dysoxia in shock sooner than currently avai
lable monitors. This allows for more timely intervention with a subseq
uent improvement in prognosis in defined groups of patients. Tonometry
data that suggest continued dysoxia despite intervention should signa
l clinicians to seek alternative diagnoses or to question the efficacy
of current therapies, including antibiotics.
