In medicine pulmonology, a pneumothorax, or collapsed lung, is a potential medical emergency caused by accumulation of air or gas in the pleural cavity, occurring as a result of disease or injury, or spontaneously.

Pneumothoraces are divided into tension and non-tension pneumathoraces. A tension pneumothorax is a medical emergency as air accumulates in the pleural space with each breath. The increase in intrathoracic pressure results in massive shifts of the mediastinum away from the affected lung compressing intrathoracic vessels. A non-tension pneumothorax by contrast is a less severe pathology because there is no ongoing accumulation of air and hence no increasing pressure on the organs within the chest. The accumulation of blood in the thoracic cavity hemothorax exacerbates the problem, creating a hemopneumothorax. Signs and symptoms Sudden shortness of breath, dry coughs, cyanosis turning blue and pain felt in the chest, back and/or arms are the main symptoms. In penetrating chest wounds, the sound of air flowing through the puncture hole may indicate pneumothorax, hence the term sucking chest wound. The flopping sound of the punctured lung is also occasionally heard. Subcutaneous emphysema is another symptom. If untreated, hypoxia may lead to loss of consciousness and coma. In addition, shifting of the mediastinum away from the site of the injury can obstruct the superior and inferior vena cava resulting in reduced cardiac preload and decreased cardiac output. Untreated, a severe pneumothorax can lead to death within several minutes. Spontaneous pneumothoraces are reported in young people with a tall stature. As men are generally taller than women, there is a preponderance among males. The reason for this association, while unknown, is hypothesized to be the presence of subtle abnormalities in connective tissue. Some spontaneous pneumothoraces however, are results of blebs, blister like structures on the surface of the lung, that rupture allowing the escape of air into the pleural cavity. Pneumothorax can also occur as part of medical procedures, such as the insertion of a central venous catheter an intravenous catheter in the subclavian vein or jugular vein. While rare, it is considered a serious complication and needs immediate treatment. Other causes include mechanical ventilation, emphysema and quite rarely other lung diseases pneumonia. Diagnosis The absence of audible breath sounds through a stethoscope can indicate that the lung is not unfolded in the pleural cavity. This accompanied by hyperresonance higher pitched sounds than normal to percussion of the chest wall is suggestive of the diagnosis. The coin test may be positive. Two coins when tapped on the affected side, produce a tinkling resonant sound which is audible on auscultation.3 If the signs and symptoms are doubtful, an X-ray of the chest can be performed, but in severe hypoxia, or evidence of tension pneumothorax emergency treatment has to be administered first. In a supine chest X-ray the deep sulcus sign is diagnostic4, which is characterized by a low lateral costophrenic angle on the affected side.5 In layman's terms, the place where rib and diaphragm meet appears lower on an X-ray with a deep sulcus sign and suggests the diagnosis of pneumothorax. Differential Diagnosis When presented with this clinical picture, other possible causes include: Acute Myocardial Infarction: presents with shortness of breath and chest pain, though MI chest pain is characteristically crushing, central and radiating to the jaw, left arm or stomach. Whilst not a lung condition, patients having an MI often happen to also have lung disease. Emphysema: here, delicate functional lung tissue is lost and replaced with air spaces, giving shortness of breath, and decreased air entry and increased resonance on examination. However, it is usually a chronic condition, and signs are diffuse not localised as in pneumothorax. Careful history taking and examination and a chest X-ray will allow accurate diagnosis. Pathophysiology Mechanics of a sucking chest wound. A. Air enters the chest through the opening in the chest wall during inspiration a. The lung collapses on the affected side b, air passes out of affected bronchus. Air enters the bronchus from the collapsed lung c and passes to the intact lung. The mediastinum shifts toward the uninvolved side d, and hemothorax occurs e. B. During expiration, air escapes through the wound a. The collapsed lung expands b. Air passes from the uninvolved side to the lung on involved side and out the trachea c. The mediastinum shifts to the involved side d, and hemothorax occurs e. Mechanics of a sucking chest wound. A. Air enters the chest through the opening in the chest wall during inspiration a. The lung collapses on the affected side b, air passes out of affected bronchus. Air enters the bronchus from the collapsed lung c and passes to the intact lung. The mediastinum shifts toward the uninvolved side d, and hemothorax occurs e. B. During expiration, air escapes through the wound a. The collapsed lung expands b. Air passes from the uninvolved side to the lung on involved side and out the trachea c. The mediastinum shifts to the involved side d, and hemothorax occurs e. The lungs are located inside the chest cavity, which is a hollow space. Air is drawn into the lungs by the diaphragm a powerful abdominal muscle. The pleural cavity is the region between the chest wall and the lungs. If air enters the pleural cavity, either from the outside open pneumothorax or from the lung closed pneumothorax, the lung collapses and it becomes mechanically impossible for the injured person to breathe, even with an open airway. If a piece of tissue forms a one-way valve that allows air to enter the pleural cavity from the lung but not to escape, overpressure can build up with every breath; this is known as tension pneumothorax. It may lead to severe shortness of breath as well as circulatory collapse, both life-threatening conditions. This condition requires urgent intervention. First Aid Chest wound Penetrating wounds also known as 'sucking chest wounds' require immediate coverage with an occlusive dressing, field dressing, or pressure bandage made air-tight with petroleum jelly or clean plastic sheeting. The sterile inside of a plastic bandage packaging is good for this purpose; however in an emergency situation any airtight material, even the cellophane of a cigarette pack, can be used. A small opening, known as a flutter valve, may be left open so the air can escape while the lung reinflates. Any patient with a penetrating chest wound must be closely watched at all times and may develop a tension pneumothorax or other immediately life-threatening respiratory emergency at any moment. They cannot be left alone. Blast injury or tension If the air in the pleural cavity is due to a tear in the lung tissue in the case of a blast injury or tension pneumothorax, it needs to be released. A thin needle can be used for this purpose, to relieve the pressure and allow the lung to reinflate. Pre-hospital care Many paramedics can perform needle thoracocentesis to relieve intrathoracic pressure. Intubation may be required, even of a conscious patient, if the situation deteriorates. Advanced medical care and immediate evacuation are strongly indicated. An untreated pneumothorax is an absolute contraindication of evacuation or transportation by flight. Clinical treatment Small pneumothoraces often are managed with no treatment other than repeat observation via Chest X-rays, but most patients admitted will have oxygen administered since this has been shown to speed resolution of the pneumothorax.6 Pneumothoraces which are too small to require tube thoracostomy and too large to leave untreated, have been aspirated with a needle to remove the pressure, although this technique is usually reserved for tension pneumothoraces. Larger pneumothoraces may require tube thoracostomy, also known as chest tube placement. If a thorough anesthetizing of the parietal pleura and the intercostal muscles is performed, the only major pain experienced should be either the injury that caused the pneumothorax or the re-expanding of the lung. Proper anesthetizing will come about by the following procedure: the needle should be inserted into the chest cavity and a negative pressure created in the syringe. While air bubbles rise into the syringe, the needle should be slowly pulled out of the cavity until the bubbles cease. The tip of the syringe that contains the anesthetic is now in the intercostal muscles. A proper and sizable injection should ensue. This will allow the patient to be fairly comfortable despite a hemostat or finger being inserted into the chest cavity. A tube is then inserted into the chest wall outside the lung and air is extracted using a simple one way valve or vacuum and a water valve device, depending on severity. This allows the lung to re-expand within the chest cavity. This re-expansion usually lasts for approximately 15-30 seconds depending on the size of the pneumothorax and feels as if your breath has been taken away. This response is normal and should pass fairly quickly. The pneumothorax is followed up with repeated X-rays. If the pneumothorax has resolved and there is no further air leak, the chest tube removed. If, during the time that the tube is still in the chest, the lung manages to sustain the re-expansion once suction is turned off, but the lung still diminishes if actually clamped off, a Heimlich valve may be used. This flutter valve allows air and fluid in the pleural cavity to escape the pleura into a drainage bag while not letting any air or fluid back in. This method was developed by the military in order to get soldiers with lung injuries stable and out of the battle field faster. It is a rarely used medical device in the treatment of patients these days, but may be used in order to allow the patient to leave the hospital. In the situation that the chest tube does not seem to be helping the healing of the lung or if CAT scans show the presence of blebs on the surface of the lung orthoscopic surgery may be done in order to staple the lung closed. Two small incisions are made in the back, one for a small camera and one for the tool used to seal the lung. When finished the wound is covered with a steri-strip and bandaged up. In case of penetrating wounds, these require attention, but generally only after the airway has been secured and a chest drain inserted. Supportive therapy may include mechanical ventilation. Recurrent pneumothorax may require further corrective and/or preventive measures such as pleurodesis. If the pneumothorax is the result of bullae, then bullectomy the removal or stapling of bullae or other faults in the lung is preferred. Chemical pleurodesis is the injection of a chemical irritant that triggers an inflammatory reaction, leading to adhesion of the lung to the parietal pleura. Substances used for pleurodesis include talc, blood, tetracycline and bleomycin. Mechanical pleurodesis does not use chemicals. The surgeon roughs up the inside chest wall parietal pleura so the lung attaches to the wall with scar tissue. This can also include a parietal pleurectomy, which is the removal of the parietal pleura; parietal pleura is the serous membrane lining the inner surface of the thoracic cage and facing the visceral pleura, which lies all over the lung surface. Both operations can be performed using keyhole surgery to minimise discomfort to the patient. Sometimes pneumothorax occurs bilaterally in sequence or, more rarely, simultaneously; that is often associated to bilateral apical blebs and obviously requires bilateral treatment 7.8 Spontaneous Pneumothorax Spontaneous Pneumothorax can be classified as primary spontaneous pneumothorax and secondary spontaneous pneumothorax. In primary spontaneous pneumothorax, it is usually characterized by a rupture of a bleb in the lung while secondary spontaneous pneumothorax mostly occurs due to chronic obstructive pulmonary disease COPD. Primary spontaneous pneumothorax A primary spontaneous pneumothorax may occur without either trauma to the chest or any kind of blast injury. This type of pneumothorax is caused when a bleb an imperfection in the lining of the lung bursts causing the lung to deflate. If a patient suffers two or more instances of a spontaneous pneumothorax, surgeons often recommend a bullectomy and pleurectomy. Primary spontaneous pneumothorax is most evident in people without any previous history of lung disease and in tall, thin men who are 20-40 years old; however it can often occur in teenagers and young adults. Secondary spontaneous pneumothorax A known lung disease is present in secondary spontaneous pneumothorax.9 The most common cause is chronic obstructive pulmonary disease COPD. However, there are several diseases that may lead to spontaneous pneumothorax: COPD Tuberculosis Pneumonia Asthma Cystic fibrosis Lung cancer Interstitial lung disease Marfan syndrome Lymphangioleiomyomatosis LAM10 History Jean Marc Gaspard Itard, a student of René Laennec, first recognised pneumothorax in 1803, and Laennec himself described the full clinical picture in 1819.11 Prior to the advent of anti-tuberculous medications, iatrogenic pneumothoraces were intentionally given to tuberculosis patients in an effort to collapse a lobe, or entire lung around a cavitating lesion. This was known as 'resting the lung'. References ^ Broome JR, Smith DJ November 1992. Pneumothorax as a complication of recompression therapy for cerebral arterial gas embolism.
