non-compressible hemorrhage
Bleeding from deep anatomical sites that cannot be controlled by external pressure or tourniquets.
Full Definition
Non-compressible hemorrhage refers to bleeding originating from deep anatomical locations such as the thorax, abdomen, pelvis, or proximal extremities where external compression cannot effectively achieve hemostasis. This type of bleeding represents one of the leading causes of preventable death in trauma and typically requires surgical intervention, angioembolization, or other advanced techniques for control. Examples include hepatic lacerations, major vascular injuries, and pelvic fractures with arterial bleeding. The concept is particularly important in military and civilian trauma care as it identifies injuries requiring immediate operative intervention.
Usage
Usage note: Always hyphenate 'non-compressible' when used as a compound adjective.
