Critically ill patients require vigilant monitoring of tissue oxygenation, particularly oxygenation of the gut mucosa, because of the mucosa's fragile blood supply. With the advent of gastric tonometry, splanchnic tissue oxygenation can be measured in a minimally invasive and cost-effective manner. Requiring only a gastric tonometer (approximately $70) and facilities to measure arterial blood gases, this method allows early detection of covert compensated shock by determining pHi. Thus, early intervention and correction of deficits in tissue oxygenation are possible and may improve patients' outcome.
重症患者需要密切监测组织氧合情况，尤其是肠黏膜的氧合，因为肠黏膜的血液供应很脆弱。随着胃张力计的出现，可以以微创且经济有效的方式测量内脏组织氧合。该方法仅需一台胃张力计（约70美元）和测量动脉血气的设备，通过测定胃内pH值就能早期发现隐匿性代偿性休克。因此，可以早期进行干预并纠正组织氧合不足的情况，这可能会改善患者的预后。
