This rather intricate connection of bones and ligaments provide the ribcage with strength, yet provide elasticity to allow the chest cavity to expand and contract during ventilation. In addition, the last two pairs of false ribs are known as floating ribs, as they do not attach to the sternum at all. These are called true ribs, compared to the remaining five pairs of false ribs which do not attach directly to the sternum. Anteriorly, the first seven rib pairs directly connect to the sternum through cartilaginous attachments. The first rib pair lies just under the clavicles. Twelve pairs of ribs connect posteriorly to the spinal column vertebrae with bands of ligaments that hold them in place. The thoracic or chest cavity is cylindrical in shape, and contains organs of the cardiovascular, respiratory and gastrointestinal systems. Together they make up almost 20 percent of all major trauma cases. The most common causes of penetrating trauma are from stabbing and gunshots. The most common cause of blunt force chest injuries is the motor vehicle crash, accounting for 70-80 percent of such injuries.

Chest injuries range from minor abrasions and contusions, to major blunt and penetrating traumatic events that cause compromise to the airway, breathing and/or perfusion. The thoracic, or chest area of the body contains major organs and structures essential to human survival and well-being. Jugular venous distention was noted, and radial pulses were weak and thready. Auscultation of the chest revealed near-absent lung sounds over the right side. The pulse oximeter provided an initial reading of 79 percent on room air. As they disrobed the patient, they determined that the patient was dyspneic, with rapid breathing. Under the bright lights of the patient care compartment, the crew noted the man was neatly dressed, although his jacket was torn and his shoes were missing. ![]() With resignation, the medics lift the patient onto their gurney and wheeled him into their unit. ![]() The man responded by grunting and feebly trying to push them away.
