Emphysema At Bronchial Asthma

Pulmonary emphysema is a serious chronic complication of bronchial asthma. At this condition the alveolus (blisters, of which lungs tissue consists) are excessively stretched and lose their ability to sufficient reduction due to what oxygen supply to blood and removal of carbon dioxide from organism worsens.

Usually lungs are affected completely (so-called diffuse emphysema). If overblown areas of lungs alternate with normal tissue, they are called bullas (globules), and emphysema is called bullous.

At narrowed fine bronchi the exhalation is more complicated than inspiration at asthma. There is an excessive air in alveolus and its pressure increases. Alveolus stretch excessively and become denser. Excess air doesn’t take part in respiration that leads to deficient work of lungs.

Patients with diffuse emphysema complain of dyspnea which becomes more intensive at exercise stress. Bullous emphysema often proceeds imperceptibly being shown by complication – a rupture of bulla with air injection into pleural cavity (development of pneumothorax). Urgent surgery is required at pneumothorax.

Emphysema without treatment progresses, work of respiratory and cardiovascular systems is broken. The patient has an expressed dyspnea, cyanotic skin (also tongue, lips, fingernails), increased thorax volume of barrel shape, decrease of respiratory movements.

Gradually progressing dyspnea turns into threat for the patient’s life.

At initial stages of disease to patients position on stomach with lowered head and shoulders gives alleviation. At severe emphysema patients are compelled even to sleep in sitting position.
