open chest wound
o·pen chest wound
/ˈōpən CHest wo͞ond/
Noun
A wound created by some type of penetrating mechanism, such as a stabbing or gunshot. An opening is created, which may not be self-sealing by the skin and muscles after the object passes through. As a result, air may leak into the chest cavity or in between the visceral and parietal pleura, creating a situation explained earlier. If an artery or vein is damaged by the mechanism, blood can also enter the cavity.
