Abstract
A method of assisting a mammal having a lung disorder to breathe ambient gas normally, i.e., without the assistance of a ventilator. The method includes providing an animal having a lung disorder, such as surfactant deficiency, stiff lung or hyperinflated lung syndrome, and instilling a perfluorochemical liquid into the trachea for administration in the alveolar sacs of a lung of the animal. The perfluorochemical is permeable to the ambient gas and resides substantially permanently within the alveolar sacs without inducing hyperinflated lung syndrome. The liquid is instilled in an amount sufficient to enable the animal to breathe the ambient gas normally with O.sub.2 /CO.sub.2 blood gas exchange. In another aspect of the invention, the method further includes the step of alleviating the lung disorder without inducing hyperinflated lung syndrome.
