An Address ON MASSIVE PULMONARY COLLAPSE

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...

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 ...

massive pericardial effusion in down syndrome with supravalvar pulmonary stenosis associated to left pulmonary collapse

background:  pericardial effusion (pe) in down syndrome (ds) patients  usually occur s   secondary to hypothyroidism,  but  we have   no  report of massive pericardial effusion in   euthyroid   down syndrome patient with  supravalvar  pulmonary stenosis . case presentation:  we  report ed   an   11-month-old  male with down syndrome   with  massive  pericardial  effusion that  had conservative ...

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...
