Oxygen Dissociation Curve (ODC): Range in human population. Data were obtained from tonometric measurements of 60 young and healthy volunteers participating in an endurance exercise study as described in Balcerek et al. ¹¹ The average ODC represents the mean of all 60 participants. To indicate the range in a human population, the ODCs of the participant with lowest and highest p₅₀ values were chosen. The higher distance of pO₂ at 75% O₂ saturation (p₇₅) compared to p₅₀ and p₂₅ (green arrows) indicate that the slope is steeper when ODC is shifting to the left
