Arterial–venous blood gas correlation and prognostic significance in critically ill pediatric patients

Key Points

• This research aims to evaluate the correlation between arterial and venous blood gas analyses in critically ill pediatric patients and their prognostic implications.
• Analyzed venous blood gas parameters including PCO2 and lactate levels in the PICU.
• Compared these parameters to arterial blood gas measures for accuracy in assessing patients.
• Investigated the utility of venous sampling in risk stratification and monitoring outcomes.
• Venous PCO2 and lactate levels showed significant correlations with arterial parameters.
• Venous sampling may serve as an alternative for specific parameters in stable patients.
• Arterial blood gas analysis remains necessary for accurate assessment of oxygenation and hypoxemia.
