Overview Lung volume reduction surgery is used to improve breathing in some people with severe emphysema, a type of During surgery, small wedges of damaged lung tissue are removed to allow the remaining tissue to function better. After surgery, people often have less shortness of breath, have better quality of life and are better able to exercise. Why it's done During lung volume reduction surgery, a chest (thoracic) surgeon removes small wedges of damaged lung tissue, usually about 20 to 30 percent of each lung, to allow the remaining tissue to function better. As a result, the diaphragm contracts and relaxes more effectively and efficiently, so you can breathe more easily. To determine whether you might benefit from lung volume reduction surgery, your doctor may recommend the following: • Imaging and physiological evaluation, including tests of your heart and lung function, exercise tests, and a computerized tomography (CT) scan of your lungs to assess the severity and location of the emphysema • Initiation of pulmonary rehabilitation, a program that empowers people to take care of themselves by increasing awareness of their physical function and emotions How you prepare Before lung volume reduction surgery, your heart and lungs may be tested to see how well they work. You may also have exercise tests and an imaging test of your lungs. You may take part in pulmonary rehabilitation, a program that helps people improve how well they function physically and emotionally. Res...

Subcutaneous emphysema ( SCE, SE) occurs when Subcutaneous refers to the subcutaneous crepitation, a form of Subcutaneous emphysema Other names Surgical emphysema, tissue emphysema, sub Q air An abdominal CT scan of a patient with subcutaneous emphysema (arrows) Numerous etiologies of subcutaneous emphysema have been described. Subcutaneous emphysema can result from puncture of parts of the surgical emphysema. spontaneous subcutaneous emphysema is used when the cause is not clear. Causes Trauma Conditions that cause subcutaneous emphysema may result from both Subcutaneous emphysema is frequently found in pneumothorax (air outside of the lung in the chest cavity) Pneumomediastinum can result from a number of events. For example, foreign body Subcutaneous emphysema of the chest wall is commonly among the first indications that Trauma to parts of the respiratory system other than the lungs, such as rupture of a Injury with Medical treatment Subcutaneous emphysema is a common result of certain types of surgery; for example it is not unusual in One of the main causes of subcutaneous emphysema, along with pneumothorax, is an improperly functioning chest tube. Since Infection Air can be trapped under the skin in Diagnosis Significant cases of subcutaneous emphysema are easy to diagnose because of the characteristic signs of the condition. The presence of subcutaneous emphysema in a person who appears quite ill and febrile after bouts of vomiting followed by left chest pain is ver...

Surgical emphysema is another term for subcutaneous emphysema. It occurs when air or gas enters the subcutaneous tissue, which is the deepest layer of the skin. People can develop surgical emphysema from injury and When a doctor treats the cause, surgical emphysema tends to resolve on its own as the body reabsorbs the gas. However, if the gas bubble is pressing against the lungs or airways, a person Read on to learn more about surgical emphysema. Share on Pinterest Suriyo Hmun Kaew/EyeEm/Getty Images A person has surgical emphysema when gas becomes trapped in According to Because the gas tends to collect in areas of the body with the least tension, it can accumulate in spaces or cavities that surround the lungs and heart. This can cause life threatening complications. The following traumas can cause surgical emphysema, according to • surfacing • • air gun injury • dental extraction • • People can also experience surgical emphysema during an operation or medical procedure. For example, when a doctor is inserting or moving a tube in the body. Examples of procedures • gastric tube placement • breathing tube placement • The Additional symptoms depend on the cause and location of swelling. For example, if the gas is trapped in the face and has moved to the eye area, a person may develop a swollen eyelid. Alternatively, if the swelling is in the throat, they may not be able to speak as they typically would. If the gas expands rapidly and fills the space around the lungs and hear...
