Respiratory Diseases

Atelectasis Atelectasis is defined as the decompose or closure of alveoli solvinging in reduced or absent gas exchange. It may clash with part or all of one lung. It is a decipher where the alveoli are deflated, as distinct from pulmonary consolidation. It is a very vulgar finding in chest x-rays and other radiological studies. It may be begind 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 more 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 chronic condition. In acute atelectasis, the lung has recently collapsed and is primarily notable unaccompanied most(prenominal) for airlessness. In chronic atelectasis, th e affected area is often characterized by a complex mixture of airlessness, infection, widening of the bronchi (bronchiectasis), destruction, and scarring (fibrosis). The most jet cause is post-surgical atelectasis, characterized by splinting, i.e. restricted breathing after fictional character AB surgery. Smokers and the elderly are at an increased risk.

exterior 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, usually squamous cell carcinoma) or compressing from the outside (tumor, lymph node, tub ercle). Another cause is poor surfactant spr! eading during inspiration, causing the surface latent hostility to be at its highest which tends to collapse smaller alveoli. Atelectasis may excessively occur during suction, as along with sputum, air is withdrawn from the lungs. on that point are several types of atelectasis according to their underlying mechanisms or the diffusion of alveolar collapse; resorption, compression, micro atelectasis and contraction atelectasis.
