Neonatal / Pediatric VBG Analyzer
Interpret neonatal and pediatric venous blood gases with age-aware acid-base framing, PvCO₂ trend guidance, bicarbonate and base excess interpretation, and clear warnings about why venous PO₂ should not be used for oxygenation decisions. Pair this with the CBG Analyzer, Cord Gas Analyzer, and Pre/Post-Ductal Analyzer for a complete neonatal gas workflow.

Typical neonatal / pediatric VBG ranges
Venous values are best used for pH, bicarbonate, base excess, and CO₂ trend. Venous PO₂ is not a substitute for PaO₂. Use these ranges as context, not a replacement for local neonatal or pediatric policy.
pH
~7.30–7.40
PvCO₂
40–55 mmHg
HCO₃⁻
20–26 mmol/L
Base excess
~−5 to +3
Neonatal venous values may run slightly more acidotic and CO₂-rich than arterial values. Need oxygenation context? Use the Pre/Post-Ductal Analyzer, P/F Ratio & Oxygenation Index, or the Neo/Peds Oxygenation Reference.

Neonatal VBGs are useful for pH, CO₂ trend, bicarbonate, and base excess — but oxygenation and delivery-room status often need paired PulmTools analyzers.
