Massive Collapse of the Lung: “Absorption Collapse”

Massive collapse of the lung

Experimental massive pulmonary collapse.

Interest in atelectasis has in recent years been revived by the increased recognition of its frequency. It has been demonstrated that complete obstruction of the air passage supplying a unit of the lung which does not also communicate with another air passage will produce atelectasis.'3 It has been shown4 that this is due to absorption by the body fluids of the gases contained in that part of t...

Acute Massive Atelectatic Collapse of the Lungs

The following case appears to be worthy of record :? Mr. N., set. 56, was admitted into hospital on 24th January, 1933, complaining of fever with rigors for the last four days. About three weeks ago the patient had a sharp attack of influenza from which he had not wholly recovered when lie got the present attack of fever. He is subject to intermittent attacks of malaria. On admission his temper...

Massive pulmonary collapse during thoracotomy.

A 28-year-old housewife was admitted to hospital in congestive cardiac failure but treatment with digitalis resulted in rapid improvement. She had a past history of attacks of winter bronchitis and rheumatic fever at 12 years of age. Clinical examination suggested that the underlying lesion was stenosis of the mitral valve, and one month later the patient was referred to a thoracic surgeon for ...

Phases of massive scalar field collapse

We study critical behavior in the collapse of massive spherically symmetric scalar fields. We observe two distinct types of phase transition at the threshold of black hole formation. Type II phase transitions occur when the radial extent (λ) of the initial pulse is less than the Compton wavelength (μ) of the scalar field. The critical solution is that found by Choptuik in the collapse of massle...
