Atelectasis vs. Emphysema

Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. It is usually unilateral, affecting part or all of one lung.

A pathological condition of the lungs marked by an abnormal increase in the size of the air spaces, resulting in labored breathing and an increased susceptibility to infection. It can be caused by irreversible expansion of the alveoli or by the destruction of alveolar walls.

The absence of gas from all or part of the lung, due to failure of expansion of the alveoli.

An abnormal distension of body tissues caused by retention of air.

A congenital condition characterized by incomplete expansion of the lungs.

(pathology) An abnormal accumulation of air or other gas in tissues, most commonly the lungs.

(medicine) The collapse of a part of or the whole lung caused by inner factors rather than a pneumothorax.

(medicine) Pulmonary emphysema, a chronic lung disease, one type of chronic obstructive pulmonary disease.

collapse of an expanded lung (especially in infants); also failure of pulmonary alveoli to expand at birth

A swelling produced by gas or air diffused in the cellular tissue.

an abnormal condition of the lungs marked by decreased respiratory function; associated with smoking or chronic bronchitis or old age
