Respiratory Diseases

Atelectasis Atelectasis is defined as the decompose or closure of alveoli essenceing in reduced or absent gas exchange. It may jar with part or all of one lung. It is a absorb where the alveoli are deflated, as distinct from pulmonary consolidation. It is a really vulgar finding in chest x-rays and other radiological studies. It may be arranged by normal exhalation or by some(prenominal) medical conditions. Although frequently described as a collapse of lung tissue, atelectasis is not synonymous with a pneumothorax, which is a to a greater extent specific condition that features atelectasis. Acute atelectasis may overtake as a post-operative complication or as a result of surface-active agent deficiency. In premature neonates, this leads to infant respiratory distress syndrome. Atelectasis may be an acute or continuing condition. In acute atelectasis, the lung has recently collapsed and is primarily notable lone(prenominal) most(prenominal) for airlessness. In chr onic atelectasis, the affected area is often characterized by a complex mixture of airlessness, infection, widening of the bronchi (bronchiectasis), destruction, and scarring (fibrosis). The most special K cause is post-surgical atelectasis, characterized by splinting, i.e. restricted breathing after part AB surgery. Smokers and the elderly are at an increased risk.

away(p) of this context, atelectasis implies some blockage of a bronchiole or bronchus, which can be at bottom the airway (foreign body, mucus plug), from the wall (tumor, commonly squamous cell carcinoma) or compressing from the outside (tumor, lymp h node, tubercle). Another cause is poor sur! factant spreading during inspiration, causing the surface latent hostility to be at its highest which tends to collapse smaller alveoli. Atelectasis may too occur during suction, as along with sputum, air is withdrawn from the lungs. at that place are several types of atelectasis according to their underlying mechanisms or the statistical distribution of alveolar collapse; resorption, compression, micro atelectasis and contraction atelectasis.
