Due to excess weight in a person, the chest wall is compacted. Superficial weakened vesicular breathing occurs as a result of the stress state of small particles of the lungs (alveoli) due to their uneven distribution.
Pathology of vesicular respiration
The causes of a pathological violation of natural respiratory noise can be as follows: insufficiently expanded lungs when breathing in; any obstruction to listening to breathing noise; difficulty in passing air masses into the lungs.
Weakened vesicular breathing
Bronchial, laryngeal, tracheal constriction leads to difficult entry of air masses into the lung area. The reason may be a postoperative scar, and blockage of foreign objects, and tumor growths. With a decrease in the larynx and tracheal organs, weakened vesicular breathing will be heard throughout the chest. The narrowing of the bronchi leads to the fact that the weakening of breathing is heard only in places of compression. Clogging with tumor growths or foreign bodies is characterized by a complete lack of listening.
Other diseases leading to a weakening of vesicular breathing:
1. Emphysema. With the loss of flexibility of the lung tissue, there is practically no expansion of the pulmonary system during inspiration.
2. Focal pneumonia. In the lungs, vesicular breathing is weakened by reducing the stress on the walls of the alveoli.
Types of breathing
- The accumulation in the pleura of liquid or air filling also leads to poor listening to breathing.
- At elevated temperature, physical exertion, intense (enhanced) vesicular breathing occurs.
- Sharp breathing with signs of roughness is called hard. In this case, it can take both a normal course and a weakened one.
- Saccade (intermittent) breathing occurs with small pauses. The reason for this is uneven muscle contraction. It indicates a narrowing of the small bronchus due to inflammatory processes. Intermittent breathing due to the passage of air into the respiratory system in several portions.
- The pathology of bronchial breathing is present when the lungs contain small densified areas containing air masses and are in contact with the bronchi. Such seals occur with heart attack, pleurisy, pneumothorax. Tuberculosis, bronchiectasis, and abscesses contribute to the formation of a cavity in the structure of the lungs.
- Mixed type. Vesicular breathing when inhaling and bronchial when exhaling. Pathology is observed in the case of alternation of compacted and normal sections of the lungs. Such symptoms are inherent in the following diseases: tuberculosis, pleural exudate and pneumonia.
Bronchial breathing
With bronchial breathing in the area of the bronchi should be complete patency. Due to the dense areas in the lungs, breathing becomes intense. Loud arises from a disease of lobar pneumonia. The metallic form of breathing (with ringing sounds) is observed with open pneumothorax.
