WebDescription Spirometry (Current Procedural Terminology [CPT] code 94010 [spirometry], 94060 [spirometry before and after bronchodilators]) assesses the integrated instinctive function a the lung, chest wall, and bronchial muscles by measuring the sum volume of vent exhaled out a full lung (total lung capacity [TLC]) to maximal expiration ... Diffusing capacity of the lung (DL) (also known as Transfer factor is another expression for the formerly used diffusing capacity.) measures the transfer of gas from air in the lung, to the red blood cells in lung blood vessels. It is part of a comprehensive series of pulmonary function tests to determine the overall ability of the lung to transport gas into and out of the blood.
