Correlation coefficient matrix of 1/Tm,CO and 1/Qc with age, height, forced expiratory volume in one second (FEV1), total lung capacity (TLC) and residual volume

AgeHeightFEV1TLCResidual volume
1/Tm,CO0.208*−0.678**−0.773**−0.743**−0.264**
1/Qc0.055−0.687**−0.699**−0.755**−0.401**
  • Tm,CO: diffusion capacity of the alveolocapillary membrane

  • Qc: pulmonary capillary blood volume

  • *: correlation is significant at 0.05 level

  • **: correlation is significant at 0.01 level
