SUMMARY Studies of total lung diffusion measured by the single-breath carbon monoxide method have been reported for 59 normal subjects between the ages of 7 and 40 years. In addition determinations of diffusing capacity of the pulmonary membrane and pulmonary capillary blood volume have been performed in 34 of the subjects. A comparison of the present results with those previously reported as well as a brief discussion of some of the limitations of the technique are presented. ___MH
