title: Pulmonary diffusing capacity and its components (DM and Vc) in young, healthy smokers.
abstract: We have studied the diffusing capacity and its components (DM and Vc) in two groups of 9 males, healthy, smokers and nonsmokers, with similar age, biometric characteristics and spirographic values. Also, BT was not different between the two groups, because the smokers were asked to stop smoking 12 h before the test. Our data showed that TF and DM are significantly lower in smokers than in nonsmokers (p less than 0.005 and less than 0.01, respectively, while Vc was not different between the two groups and confirm that Vc is influenced by COhb level.
