T79: Certain early complications of trauma, not elsewhere classified
T79.7: Traumatic subcutaneous emphysema
When we breathe, the air gets into the body via the respiratory tract. The respiratory tract can be divided into the upper and the lower respiratory tracts. The nose and throat form part of the upper respiratory tract. The lower respiratory tract begins at the larynx. This includes the trachea and the bronchia.
If injury occurs to the trachea, bronchia or lungs, air can get into the surrounding tissue. The air can collect in the surrounding tissue beneath the skin.
A swelling may be noticed beneath the skin. The swelling can be pressed away with the finger. Pressing on the swelling may produce a crackling sound.
