The clinical results and symptoms will manifest based on the degree of collapse of the lung. In the case of Mr. Richards, it is the left lung that is affected and hence symptoms are observed accordingly. His neurological symptoms show that his left leg has mild weakness and his left arm has severe weakness, while his right leg and his right arm are restored to normal power. There is a humerical shaft fracture that seems to have compounded the hemodynamic stability of lungs. Where in a normal condition a negative intrapleural pressure will exist between the pleural walls (Sideras, 2011), in the case of Mr. Richards this state has been compromised.
There are different types of pneumothorax and based on the type the symptoms would vary, some of the types are more life threatening than others (Sideras, 2011). Tension pneumothorax is one that is caused by hypotension, chest pain and dyspnea. The pneumothorax caused in the patient is because of a trauma to the chest (Cheatham, & Safcsak, 1999 p. 1160). This pneumothorax type can develop into a tension pneumothorax. “A pneumothorax is defined as the presence of air between parietal and visceral pleural cavity. Tension pneumothorax is the accumulation of air under pressure in the pleural space.
