title: [Hemoglobin oxygen combining capacity power. Reproducibility, variability; the effect of carboxyhemoglobin (author's transl)].
abstract: Hemoglobin oxygen combining power (HOCP) was measured in blood samples of 41 non smoking subjects and 36 smokers. The reproductibility and the varibility of this value were established (maximal variability was 2,5% in individual measurement). When the oxygen carrying capacity is reported to total hemoglobin (Hbt.), these two groups are not significantly different (1,344 +/- 0,004 ml O2 g-1 Hbt--n = 77-). However, when oxygen carrying capacity is reported to functional hemoglobin (Hbf = Hbt -- HbCO) there is a significative difference between smokers and non smokers (Student's t test 2 p less than 0,001) (1,404 +/- 0,005 ml O2 Hbf -- n = 77-).
