Studies of arterialized capillary blood gases and acid-base values were performed on 712 normal persons who were between the ages of 29 days and 24 years. The results were divided for clinical use into six groups by age; linear regression lines were constructed for better understanding of the development of blood gas levels and the acid-base balance. ⋯ The probable explanation for the lower values in infants is discussed. The effects of crying on the composition of blood gases are mentioned.
