What is the normal compartment pressure threshold measured in mmHg?

The normal compartment pressure threshold is generally defined as being around 10 mmHg. Compartment syndrome occurs when the pressure within a closed muscle compartment rises to a level that compromises the circulation and function of the tissues within that space.

In normal physiology, muscle and nerve tissues can sustain normal function when the intracompartmental pressure is below this threshold. When the pressure exceeds 10 mmHg, it can begin to impair blood flow, leading to ischemia. This is particularly crucial in cases of trauma or conditions that may cause swelling, as early recognition of elevated compartment pressure is key to preventing irreversible damage.

Values higher than 10 mmHg, such as 15 mmHg or 20 mmHg, are indicative of potential compartment syndrome and necessitate further evaluation and possible intervention. Distinction between these values is essential for medical professionals in diagnosing and managing the condition.
