Abstract

Method and apparatus for coating the airways of the lung of a patient substantially uniformly with a mist formed by aspirating a liquid which includes restricting the maximum size of the particles of the mist to about 1.2 microns with the major portion of the particles being in the range of .056 microns to 1 micron causing the mist to behave as a gas, conduits (21, 28, 29) for feeding the mist together with a gas containing oxygen to a patient to be inhaled during the normal breathing process, and valves (15, 17, 31) connected with the conduits for diverting the exhaled mist and gas through a discharge path. By radioactively tagging the liquid prior to production of the mist, the uniform deposition of the mist throughout the entire lung without encountering heavy accumulations in the large airways and at branch points, enables the production of high definition image scans of the lung.
