Description of pneumothorax: types of disease, causes, diagnosis and treatment

In many TV series about doctors and detectives, we oftenwe meet words whose meaning we understand poorly or do not understand at all. For example, pneumothorax. What is this disease? Symptoms, signs by which the ambulance staff so accurately determine its availability, the amount of assistance and many other aspects of this issue remain behind the scenes. In this article you will find answers that help you navigate in a critical situation.


Pneumothorax is the accumulation of air or othergas in the chest cavity. Most often occurs after injuries as a result of open fracture of the ribs or injury of the lung to a fragment of bone, as well as a rupture of the lung abscess, opening of the bullae or melting of the bronchus wall by a malignant neoplasm. Secondary pneumothorax is a continuation of a protracted lung disease.

pneumothorax types

Clinical manifestations of this symptom depend onfirst of all, on how quickly the air fills the pleural cavity. In most cases, you can make a diagnosis after examining the patient at the scene. Sometimes additional methods of examination are required, for example, radiography.

Treatment, as a rule, is surgical. It reduces to the removal of air from the cavity of the thorax by drainage or puncture, the restoration of the function of the organs of the mediastinum and their return to their places.

Relationship with the external environment

In form, there are several variationspneumothorax. The types of disease depend on which side the hole was formed (from the outside or from the inside of the body), as well as from its size and speed of gas supply.

  • Closed pneumothorax is diagnosed in thosecases where a small amount of gas enters the pleural cavity through a small hole that does not communicate with the external environment. The pressure in the chest cavity increases slowly, and the defect closes itself, without additional help. Air bubbles gradually dissolve between the pleura sheets, and the lung takes its usual shape.
  • Open pneumothorax develops under the conditionpenetrating wound of the thoracic wall or rupture of the large bronchus. Always communicates with the external environment. Because of this, the negative pressure in the internal cavity of the body aligns with the atmospheric, from which the lung collapses, and air does not enter it.

pneumothorax types of acute care

  • Stressed, or valve pneumothoraxappears only with a combined trauma (injury of the chest wall with pleural damage and rupture of the large bronchus) and is characterized by the fact that air enters the body cavity on inhalation, but does not leave it when exhaled. The pressure in the pleural cavity is first compared with the atmospheric and continues to grow. As a result, the organs of the mediastinum are displaced and squeezed.


In order to competently provide assistance,It is necessary to know how the pneumothorax forms, its types. The physiology of this process is that the normal pressure inside the pleural cavity is negative. This helps maintain the lungs in straightened condition, and also accelerates gas exchange in the alveoli. When the tightness of the chest is broken, and the atmospheric air begins to fill the pleural cavity, the lungs decrease in volume.

pneumothorax types emergency first aid

This prevents normal breathing, and inAs a result, a person begins to suffocate. In addition, the air squeezes and pushes the organs of the mediastinum: the heart, the aorta, the esophagus, interfering with the performance of their immediate functions.


From traumatizing agent depends also what will bepneumothorax. Etiology, types, pathogenesis, clinic and treatment are an inseparable logical chain, the knowledge of which can save a person's life, even if you are not related to the profession of a doctor.

1. Spontaneous pneumothorax is a rupture of a large bronchus or parenchyma of the lung that is not associated with mechanical damage to the chest. It is divided into two large groups:

  • Primary, or idiopathic, occurs withoutobvious reasons. It is more common in young tall men than in women of the same age and complexion. This can be explained by the following features: pathological changes in the lungs due to a genetic defect in the synthesis of the enzyme alpha-1-antitrypsin, which is involved in the normal functioning of the alveoli; too thin pleura, which can tear from a slight pressure drop, for example, when coughing or sneezing; sharp pressure drop when climbing mountains (mountain sickness) or submerging under water (caisson disease).pneumothorax its kinds of physiology
  • Secondary pneumothorax is formed against the background of already existing lung pathology, such as COPD (chronic obstructive pulmonary disease), cystic fibrosis and bronchial asthma.

2. The most common cases are traumatic pneumothorax. Types of damage are divided into two categories: penetrating injuries of the chest cavity (cut, chopped wounds, open fractures of the ribs); blunt injuries of the chest (auto-trauma, crushing between fixed objects, falling from height).

3. During the medical procedures, the appearance of pneumothorax is also possible. In such cases it is called iatrogenic. Danger is represented by lung or pleural biopsies, diagnostic puncture of the contents of abscesses and cysts, setting of a subclavian catheter and barotrauma from mechanical ventilation (artificial lung ventilation).


When a patient is questioned and examined, the doctor drawsattention to sudden pain in the chest, shortness of breath, rapid breathing and palpitation, dry cough. Acute attacks of fear can also be a consequence of pneumothorax. The types of injuries and the nature of damage, sometimes even visually detected, will help to finally determine the diagnosis and send the patient to treatment. It can be either a surgical or a therapeutic hospital or a resuscitation department. Everything depends on the severity of the condition and the specific damage.

types of pneumothorax first aid


As already mentioned above, knowing the mechanism by whichwas caused by pneumothorax, species and diff. diagnosis is not difficult. To do this, it is sufficient to perform an external examination of the chest and auscultation of symmetrical areas of the lungs (to compare the healthy part with the patient). If the damage was not found, then in order to be completely sure, it is necessary to send the patient to a radiography or computed tomography. The air does not reflect radioactive radiation, which means it will be clearly visible in the picture.

As an additional technique, you canuse the definition of the gas composition of the blood (to determine if there are sudden shifts towards hypercapnia), electrocardiography (to prevent complications in the form of cardiac arrest), and also to consult a surgeon (usually at the examination stage of the patient in the admission department).

Urgent care

Despite the different types of pneumothorax,first aid is reduced to an emergency call. Since an unprepared person can cope with internal injuries, it is unlikely that he will need the experience of a trauma surgeon. The only thing that can be done in case of an open variant of the disease is to impose a thick hermetically sealed bandage on the wound. To do this, you can use oilcloth, polyethylene film or thick cotton-gauze swab. These manipulations will help to form a closed pneumothorax.

pneumothorax etiology

Kinds, urgent first aid andElementary diagnosis of this disease should be included in the scope of knowledge of any person who has undergone a course of civil defense (civil defense). Then he will be able to adequately assess the situation and make the right decision.


First of all, you need to know exactly which speciespneumothorax in the patient. If the amount of air between the pleural leaves is insignificant, then specific assistance may not be required. He himself will gradually resolve. In the case where the volume of gas prevents the lung from opening normally, it must be aspirated using a syringe by puncturing the pleural cavity. This will help to quickly eliminate pneumothorax. Types (emergency care depends on it), diseases are important because they require a different approach. A significant amount of damage may require installation of a one-way drain on the Bulau.

In addition, with massive injuries, the surgeon's intervention is required to suture the lung parenchyma, pleural and bronchial defects, and also to close the penetrating wound of the chest.

pneumothorax types and diff diagnosis

As a symptomatic therapy is recommendeduse painkillers and inhalation of oxygen. If episodes of pneumothorax are repeated quite often, a patient may be recommended to perform pleurodesis - soldering the pleura sheets between them.

Complications and prognosis

Like after any illness, there are alwaysconsequences of the transferred pneumothorax. His species play an insignificant role in this case. In the first place among the complications is bleeding, or hemothorax. He was followed by pleurisy (inflammation of the connective tissue and the formation of adhesions between the pleura sheets) and subcutaneous emphysema (air entering the cellulose under the skin). With a large area of ​​damage and untimely care, the patient may die.


In order to prevent the development of pneumothorax, it is sufficient to observe a few simple rules:

  • Timely and fully treat respiratory system diseases and prevent their complications leading to the formation of weak spots in the lungs and pleura.
  • Refuse bad habits, in particular - from smoking.
  • Try to avoid traumatizing the chest.
  • Take measures to avoid repeated pneumothorax.
