Abstract
The clinical significance of spirometry in disease was recognized more than sixty years ago, but in the last decade little attention has been devoted to its practical application. Recently, however, a number of studies on the respiration have again indicated that the character and possible extent of the pulmonary ventilation are intimately related to the vital capacity of the lungs, and that determination of the vital capacity gives important information as to the functional efficiency of the lungs. Clinical observations have shown that the vital capacity of the lungs is of especial interest in pulmonary tuberculosis1and in heart disease,2and that in both these conditions it serves as an index of the clinical condition of the patient. As the disease becomes more severe, the vital capacity falls, and as the disease improves, the vital capacity increases and approaches the normal. In pulmonary tuberculosis and in the other inflammatory orThis publication has 0 references indexed in Scilit:
