Damage "does not necessarily imply total loss of system functionality, but rather that the system is no longer operating in its optimal manner". [1] Damage to physical objects is "the progressive physical process by which they break", [2]: 1. and includes mechanical stress that weakens a structure, even if this is not visible. [2]: ix.
The decision whether to perform surgery is determined by the extent of the damage and the anatomical location of the injury. Bleeding must be controlled before definitive repair may occur.

Depending on the extent of injury, the cellular response may be adaptive and where possible, homeostasis is restored. [1] Cell death occurs when the severity of the injury exceeds the cell's ability to repair itself. [2] Cell death is relative to both the length of exposure to a harmful stimulus and the severity of the damage caused. [1]
The most immediate injury caused by asphyxia is hypoxia, which can in turn cause acute lung injury or acute respiratory distress syndrome as well as damage to the circulatory system. The most severe injury associated with asphyxiation is cerebral hypoxia and ischemia , in which the brain receives insufficient oxygen or blood, resulting in ...
