What is a hematoma?

A hematoma is defined as a localized collection of blood that accumulates beneath the skin, typically due to the rupture of blood vessels. This condition often occurs after an injury or trauma, which causes blood to leak into the surrounding tissues. The pooling of blood forms a distinct area that can be swollen and discolored, often appearing as a bruise.

The essential aspect of a hematoma is its nature of being a confined area of blood, differentiating it from other types of injuries or conditions. Understanding this definition is crucial for emergency medical responders, as it helps in assessing injuries and determining the severity of trauma. Knowing how to identify and differentiate a hematoma from other conditions is fundamental for effective patient care.
