Pneumothorax - Wikipedia. A pneumothorax is an abnormal collection of air in the pleural space that causes an uncoupling of the lung from the chest wall. Like a pleural effusion (liquid buildup in that space), a pneumothorax may interfere with normal breathing. Symptoms typically include chest pain and shortness of breath. It is often called a collapsed lung, although that term may also refer to atelectasis. One or both lungs may be affected. A primary pneumothorax is one that occurs without an apparent cause and in the absence of significant lung disease, while a secondary pneumothorax occurs in the presence of existing lung disease. A pneumothorax can be caused by physical trauma to the chest (including a blast injury), or as a complication of a healthcare intervention; in which case it is called a traumatic pneumothorax. In a minority of cases the amount of air in the chest increases markedly when a one- way valve is formed by an area of damaged tissue, leading to a tension pneumothorax. This condition can cause a steadily worsening oxygen shortage and low blood pressure. Punctured Artefact creates handmade tattooed and tooled leather art.

Unless reversed by effective treatment, it can result in death. Diagnosis of a pneumothorax by physical examination alone can be difficult (particularly in smaller pneumothoraces). A chest X- ray, computed tomography (CT) scan, or ultrasound is usually used to confirm its presence. Small spontaneous pneumothoraces typically resolve without treatment and require only monitoring. Being a healthcare proxy and making end-of-life care decisions on behalf of someone you love can be challenging. Learn more about what to expect.This approach may be most appropriate in people who have no underlying lung disease. In a larger pneumothorax, or when there are marked symptoms, the air may be removed with a syringe or a chest tube connected to a one- way valve system. Occasionally, surgery may be required if tube drainage is unsuccessful, or as a preventive measure, if there have been repeated episodes. The surgical treatments usually involve pleurodesis (in which the layers of pleura are induced to stick together) or pleurectomy (the surgical removal of pleural membranes). Signs and symptoms. Chest pain and sometimes mild breathlessness are the usual predominant presenting features. Symptoms in SSPs tend to be more severe than in PSPs, as the unaffected lungs are generally unable to replace the loss of function in the affected lungs. Punctured: When a killed image is not dead.

Pop off one side of the tyre, as above, and remove the punctured tube. Again, don’t forget to check the tyre for what caused the puncture and remove that, too. Hypoxemia (decreased blood- oxygen levels) is usually present and may be observed as cyanosis (blue discoloration of the lips and skin). Hypercapnia (accumulation of carbon dioxide in the blood) is sometimes encountered; this may cause confusion and - if very severe - may result in comas. The sudden onset of breathlessness in someone with chronic obstructive pulmonary disease (COPD), cystic fibrosis, or other serious lung diseases should therefore prompt investigations to identify the possibility of a pneumothorax. Traumatic pneumothoraces have been found to occur in up to half of all cases of chest trauma, with only rib fractures being more common in this group. The pneumothorax can be occult (not readily apparent) in half of these cases, but may enlarge - particularly if mechanical ventilation is required. Measures of the conduction of vocal vibrations to the surface of the chest may be altered. Percussion of the chest may be perceived as hyperresonant (like a booming drum), and vocal resonance and tactile fremitus can both be noticeably decreased. Importantly, the volume of the pneumothorax can show limited correlation with the intensity of the symptoms experienced by the victim. Other findings may include quieter breath sounds on one side of the chest, low oxygen levels and blood pressure, and displacement of the trachea away from the affected side. Rarely, there may be cyanosis (bluish discoloration of the skin due to low oxygen levels), altered level of consciousness, a hyperresonant percussion note on examination of the affected side with reduced expansion and decreased movement, pain in the epigastrium (upper abdomen), displacement of the apex beat (heart impulse), and resonant sound when tapping the sternum. Deviation of the trachea to one side and the presence of raised jugular venous pressure (distended neck veins) are not reliable as clinical signs. The most common is chronic obstructive pulmonary disease (COPD), which accounts for approximately 7. The hereditary conditions. The administration of positive pressure ventilation, either mechanical ventilation or non- invasive ventilation, can result in barotrauma (pressure- related injury) leading to a pneumothorax. Divers breathing compressed air (such as when scuba diving) may suffer a pneumothorax as a result of barotrauma from ascending just 1 metre (3 ft) while breath- holding with their lungs fully inflated. A chest tube is in place (small black mark on the right side of the image), the air- filled pleural cavity (black) and ribs (white) can be seen. The heart can be seen in the center. The thoracic cavity is the space inside the chest that contains the lungs, heart, and numerous major blood vessels. On each side of the cavity, a pleural membrane covers the surface of lung (visceral pleura) and also lines the inside of the chest wall (parietal pleura). Normally, the two layers are separated by a small amount of lubricating serous fluid. The lungs are fully inflated within the cavity because the pressure inside the airways is higher than the pressure inside the pleural space. Despite the low pressure in the pleural space, air does not enter it because there are no natural connections to an air- containing passage, and the pressure of gases in the bloodstream is too low for them to be forced into the pleural space. In secondary spontaneous pneumothoraces, vulnerabilities in the lung tissue are caused by a variety of disease processes, particularly by rupturing of bullae (large air- containing lesions) in cases of severe emphysema. Areas of necrosis (tissue death) may precipitate episodes of pneumothorax, although the exact mechanism is unclear. In PSP, blebs can be found in 7. PSP. The body compensates by increasing the respiratory rate and tidal volume (size of each breath), worsening the problem. Unless corrected, hypoxia (decreased oxygen levels) and respiratory arrest eventually follow. In tension pneumothorax, X- rays are sometimes required if there is doubt about the anatomical location of the pneumothorax. The left thoracic cavity is partly filled with air occupying the pleural space. The mediastinum is shifted to the opposite side. These are usually performed during maximal inspiration (holding one's breath); no added information is gathered by obtaining a chest X- ray in expiration (after exhaling). This is not equivalent to a tension pneumothorax, which is determined mainly by the constellation of symptoms, hypoxia, and shock. This is relevant to treatment, as smaller pneumothoraces may be managed differently. An air rim of 2 cm means that the pneumothorax occupies about 5. In some lung diseases, especially emphysema, it is possible for abnormal lung areas such as bullae (large air- filled sacs) to have the same appearance as a pneumothorax on chest X- ray, and it may not be safe to apply any treatment before the distinction is made and before the exact location and size of the pneumothorax is determined. In presumed primary pneumothorax, it may help to identify blebs or cystic lesions (in anticipation of treatment, see below), and in secondary pneumothorax it can help to identify most of the causes listed above. Several particular features on ultrasonography of the chest can be used to confirm or exclude the diagnosis. Treatment is determined by the severity of symptoms and indicators of acute illness, the presence of underlying lung disease, the estimated size of the pneumothorax on X- ray, and - in some instances - on the personal preference of the person involved. If mechanical ventilation is required, the risk of tension pneumothorax is greatly increased and the insertion of a chest tube is mandatory. Ideally, a dressing called the . The Asherman seal is a specially designed device that adheres to the chest wall and, through a valve- like mechanism, allows air to escape but not to enter the chest. This may be required before transport to the hospital, and can be performed by an emergency medical technician or other trained professional. This approach is most appropriate if the estimated size of the pneumothorax is small (defined as < 5. Further investigations may be performed as an outpatient, at which time X- rays are repeated to confirm improvement, and advice given with regard to preventing recurrence (see below). This would mean that even a complete pneumothorax would spontaneously resolve over a period of about 6 weeks. Admission to the hospital is usually recommended. Oxygen given at a high flow rate may accelerate resorption as much as fourfold. This involves the administration of local anesthetic and inserting a needle connected to a three- way tap; up to 2. If there has been significant reduction in the size of the pneumothorax on subsequent X- ray, the remainder of the treatment can be conservative. This approach has been shown to be effective in over 5. These are typically inserted in an area under the axilla (armpit) called the . Local anesthetic is applied. Two types of tubes may be used. In spontaneous pneumothorax, small- bore (smaller than 1. F, 4. 7 mm diameter) tubes may be inserted by the Seldinger technique, and larger tubes do not have an advantage. They are connected to a one- way valve system that allows air to escape, but not to re- enter, the chest. This may include a bottle with water that functions like a water seal, or a Heimlich valve. They are not normally connected to a negative pressure circuit, as this would result in rapid re- expansion of the lung and a risk of pulmonary edema (. The tube is left in place until no air is seen to escape from it for a period of time, and X- rays confirm re- expansion of the lung. Negative pressure suction (at low pressures of . Failing this, surgery may be required, especially in SSP.
