Two asthmatic children developed a pneumoperitoneum whilst being mechanically ventilated. A quick and accurate diagnosis as to the cause of the pneumoperitoneum was made by analysing the partial pressure of oxygen in the intraperitoneal free gas. This analysis helped to diagnose an intestinal perforation in one child and an air leak from lung barotrauma in the other. There was minimal delay in the surgical treatment of the child with intestinal perforation and in the other, an unnecessary laparotomy was avoided.
两名哮喘儿童在机械通气期间出现气腹。通过分析腹腔游离气体中的氧分压，对气腹的病因做出了快速准确的诊断。这一分析有助于诊断出一名儿童为肠穿孔，另一名儿童为肺气压伤导致的气体泄漏。肠穿孔儿童的手术治疗延迟极小，而另一名儿童则避免了不必要的剖腹手术。
