Hemopneumothorax is a medical problem where the lung is damaged and the chest fills up with air and blood. It is treated by opening the chest and putting in a chest drain. This can only be done by paramedics or doctors. A hemopneumothorax often happens after high speed crashes and penetrating chest wounds.
