Lin Feng discovered that the patient's abdomen was bulging and the abdominal muscles were tense, which logically shouldn't have been the case.
The patient had suffered cardiac trauma, and a CT scan of the abdomen had been conducted previously, revealing no issues. However, why were the patient's vital signs still unstable several days after the surgery, and why was the abdomen presenting in this current state?
"Measure the intra-abdominal pressure," Lin Feng pondered with doubt. The "Technique of Inner and Outer Understanding" had limited effects on such subtle issues. The patient's pulse showed no serious problems either. Out of sheer necessity, Lin Feng had no choice but to ask a nurse standing beside him to check the patient's intra-abdominal pressure.
Normally, people have a constant value for intra-abdominal pressure, within which the internal organs are neither compressed nor displaced.
