Sudden shortness of breath and cyanosis (turning blue) are the main symptoms. In penetrating chest wounds, the sound of air flowing through the punction hole may indicate pneumothorax. The flopping sound of the punctured lung is occasionally heard.
If untreated, the hypoxia will lead to loss of consciousness and coma. In addition, shifting of the mediastinum towards the site of the injury can obstruct the aorta and other large blood vessels, depriving distal tissues of blood. 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 supposed to be the presence of subtle abnormalities in connective tissue.
Pneumothorax can also occur as part of medical procedures, such as the insertion of a central line (an intravenous catheter) in the subclavian vein . While rare, it is considered a serious complication and needs immediate treatment. Other causes include mechanical ventilation, emphysema and rarely other lung diseases ( pneumonia).
The absence of audible breath sounds through a stethoscopeThe stethoscope is an acoustic medical device for auscultation i. listening to internal sounds in the human body. It is most often used to listen to heart sounds and breathing, though it is also used to listen to intestines and to blood flow in arteries a indicates that the lung is not unfolded in the pleural cavity. If the symptoms are doubtful, an X-rayIn the NATO phonetic alphabet, X-ray represents the letter X. Rontgen An X-ray is a form of electromagnetic radiation with a wavelength approximately in the range of 5 pm to 10 nanometers (corresponding to frequencies in the range 30 PHz to 60 EHz). X-ray of the chest can be performed, but in severe hypoxia, emergency treatment has to be administered first.
The lungs are located inside the chest cavity, which is a hollow space. Air is drawn into the lungs by the diaphragmIn the anatomy of mammals, the diaphragm is a shelf of muscle extending across the bottom of the ribcage. Its latin name is the transversus thoracis''. It separates the thoracic cavity (with lung and heart) from the abdominal cavity (with liver, stomach, (a powerful abdominalThe abdomen (from the Latin word meaning "belly") is the part of the body between the pelvis and the thorax. The front of the abdomen is the abdominal cavity, which is separated from the thoracic cavity by the diaphragm. The lining of the abdomen is calle muscleskeletal muscle Muscle is one of the four tissue types. The other three types are: epithelium, connective tissue and nervous tissue. The primary purpose of muscle tissue is to contract. Muscle contraction is used to move parts of the body, as well as to m). The pleural cavityIn anatomy, the pleural cavity is the potential space between the lungs and the chest wall. It has virtually nothing in it in the normal non-diseased state, except a small amount of pleural fluid . The cavity is lined by specialized epithelium called pleu is the region between the chest wall and the lungs. If air enters the pleural cavity, either from the outside or from the lung, the lung collapses and it becomes mechanically impossible for the injured person to breathe, even with a patent airwayThe airway s are those parts of the respiratory system through which air flows between the external environment and the alveoli. Protection of the airways #The epithelial surfaces of the airways contain cilia. Particles such as dust sticks to mucous which.
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.
Small pneumothoraces often resolve spontaneously and may require no other treatment than clinical observation. A large pneumothorax or tension pneumothorax is a medical emergency and may require surgery.
