This is a life-threatening emergency. Symptoms typically include sudden onset of sharp, one-sided chest pain and shortness of breath. Tension pneumothorax. In a minority of cases, a one-way valve is formed by an area of damaged tissue, and the amount of air in the space between chest wall and lungs increases; this is called a tension pneumothorax. 19-2 ). Key Clinical Message . A tension pneumothorax, the likely cause of this patient's arrest, should be rare. Pneumothorax, also called a collapsed lung, is when air gets between one of your lungs and the wall of your chest. A pneumothorax is an abnormal collection of air in the pleural space between the lung and the chest wall. The reason hinges on the creation of a one-way valve into the area between lungs and rib cage—the pleural space. Tension pneumothorax: This is a life-threatening condition that is more likely to occur with traumatic pneumothorax (after a bullet or knife wound to the chest) or in patients on mechanical ventilation (a breathing machine) than with other kinds of pneumothorax. The pressure causes the lung to give way, at least partly. Many things can cause a one-way valve. Tension Pneumothorax. Any type of pneumothorax can progress to tension pneumothorax, which is a life-threatening variant of pneumothorax. Symptoms. Treatment options may include observation, needle aspiration, chest tube insertion, nonsurgical repair or surgery. The underlying cause is usually a pulmonary laceration or an injury to the trachea or a large bronchus. Thus, many experts believe that the distinction between pneumothorax in patients “without” lung disease (ie, pneumothorax with subpleural blebs, also known as PSP) and pneumothorax in patients with lung diseases (ie, SSP) is somewhat artificial, and that PSP and SSP may exist on either end of a continuum [ 6 ]. We present a case of tension pneumothorax in a patient with COVID-19 pneumonia and myocarditis. A tension pneumothorax is a life-threatening situation. It may present with either a closed or open chest injury. Depending on the cause of the pneumothorax, a second goal may be to prevent recurrences. Some type of disruption of the pleural space-air or blood-causes the lung to begin shifting to the opposite side. What causes a tension pneumothorax? A one-way valve mechanism prevents air from escaping the pleural cavity. The methods for achieving these goals depend on the severity of the lung collapse and sometimes on your overall health. Patients with pneumothorax usually present with sudden-onset dyspnea , ipsilateral chest pain , diminished breath sounds, and hyper-resonant percussion on … A tension pneumothorax can cause complete collapse of the nearby lung and can push the heart and major blood vessels to the other side of the chest. Tension pneumothorax is an uncommon presentation in patients with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) or COVID-19 pneumonia. Tension pneumothorax may develop when a one-way valve effect occurs, allowing air to enter the pleural space but not to escape (Fig. And the more that lung shifts, the more pressure to the heart, great vessels and opposite lung. In tension pneumothorax, air continues to leak into the pleural space until the pleural pressure rises to the point that it compresses the veins and impairs venous filling of the right heart. The medical provider needs to be keenly aware that there is a high probability of a tension pneumothorax if the patient has an open trauma to the chest wall. Tension pneumothorax most commonly occurs in people with penetrating chest injuries. i ... Once stabilized, the cause must be established and repaired or resected surgically if condition persists, or primary lesions are identified that are causing air leakage, eg rupture lung abscess.
