Analysis evaluates blood gas parameters in pediatric patients, suggesting venous measures for monitoring.
Venous blood gas analysis reliably reflects acid-base status and may be an alternative to arterial sampling for selected parameters in critically ill pediatric patients. Venous PCO₂, lactate levels, and Pv-aCO₂ may be useful for risk stratification and longitudinal monitoring in the PICU. However, arterial analysis remains essential for oxygenation, and venous sampling should not substitute arterial measurements when evaluating hypoxemia.
