Spontaneous pneumothorax - a medical emergency characterized by signs of penetration of air into the pleural cavity due to violation of the integrity of the pleural sheets as a result of the formation of symptoms posts with the atmosphere through defects in the lung tissue (eg, the gap bullae), trachea and bronchi with spontaneous pneumothorax.In this article we will discuss the symptoms of spontaneous pneumothorax, and the main features of spontaneous pneumothorax in humans.In addition, we will discuss how to identify a pneumothorax.
Spontaneous pneumothorax - Symptoms Symptoms
valve spontaneous pneumothorax, as well as other kinds of it, usually develops in the background of well-being or the satisfactory condition of the patient.Suddenly, there are signs of a spontaneous pneumothorax as a chest pain, dyspnea, tachypnea, anxiety and fatigue.The nature of the symptom of shortness of breath inspiratory, the patient wants to breathe, but could not.On examination can detect signs of a chest asymmetry,
Spontaneous pneumothorax - signs
Depending on the pathogenesis distinguish 3 clinical-renttenologicheskih sign of spontaneous pneumothorax - open, closed, and the valve.
Signs Open spontaneous pneumothorax
If communication between the pleural cavity and the alveolar space through a defect of visceral pleura is saved to inhale and exhale, this leads to the development of symptoms of an open pneumothorax - air enters freely in the pleural cavity during inspiration, while exhaling out.Easy collapses, mediastinal organs are not displaced.
Signs closed spontaneous pneumothorax
Communication between the pleural cavity and the alveolar space is temporary and spontaneously stops, so the new portion of air in the pleural cavity is not being received.Such spontaneous pneumothorax can be resolved naturally (if the volume of air does not exceed 1.5 liters).Artificial therapeutic pneumothorax is closed.
Symptoms valve spontaneous pneumothorax
If the defect is the visceral pleura opens on inspiration and closes on exhalation, the valve is formed (busy, valve) spontaneous pneumothorax - air enters the pleural cavity during inspiration, it does not go out during exhalation.At the same time after each respiratory cycle is increasing the volume of gas in the pleural cavity.Symptom intrapleural pressure increases and exceeds the atmospheric pressure, ie,It becomes positive.Increased pressure displaces the mediastinum in a healthy way.If you do not evacuate the air, then there are symptoms of spontaneous pneumothorax: compression of, for example, large vessels, nerve plexus and violation of vital body functions.
How to pneumothorax - research methods signs of spontaneous pneumothorax
diagnosis of spontaneous pneumothorax confirmed radiographically, most significantly in the dynamic study, which is enough to routine X-ray.On the X-ray clearly visible boundary preloaded air light, outside from which there is no pulmonary drawing.A similar pattern was observed with CT, which is used in emergency situations often.For the valve characteristic symptoms of pneumothorax - X-ray negative dynamics within a few hours after the initial manifestation of this immediate condition: the volume of air in the pleural cavity increases, mediastinal organs are displaced in the opposite direction.
