What is the normal value of intra-abdominal pressure in cmH2O?
Intra-abdominal pressure typically ranges between 0–12 cmH₂O. Abnormal values may lead to various physical discomforts. The details are as follows:
Measurement of intra-abdominal pressure can be performed using methods such as catheters or bladder catheters, and is commonly used in monitoring ventilator-associated lung injury, liver failure, abdominal compartment syndrome, and other conditions in patients on mechanical ventilation. Under normal circumstances, intra-abdominal pressure in the human body usually remains within the range of 0–12 cmH₂O. However, patients should be aware that normal values may vary due to individual differences, measurement techniques, and other factors. If tests reveal abnormally elevated intra-abdominal pressure exceeding the normal range, it may adversely affect multiple organ systems, including cardiac function, pulmonary respiration, and renal metabolism. In severe cases, it may lead to various complications. Therefore, high-risk individuals—such as those who have undergone abdominal surgery, suffered trauma, or have infections—should undergo regular monitoring of intra-abdominal pressure, with timely interventions implemented to maintain pressure within the normal range.
If a patient shows abnormal intra-abdominal pressure readings, they should promptly cooperate with their physician to complete relevant examinations and receive targeted treatment to avoid disease progression.
