A comparison of arterial and non-arterialized capillary blood gases in diabetic ketoacidosis. 1988

The results of acid-base and blood gas estimations in arterial and non-arterialized capillary blood have been compared in samples obtained simultaneously from patients presenting with diabetic ketoacidosis. Highly significant correlations were obtained for pH, pCO2 and bicarbonate measurements. Small but significant differences were observed with capillary pH slightly lower and capillary pCO2 and bicarbonate slightly higher than arterial values. These differences were of no clinical significance. Non-arterialized capillary samples are a reliable indicator of acid-base status in this form of metabolic acidosis and are preferable to repeated arterial puncture.

UI	MeSH Term	Description	Entries
D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
