Transcutaneous CO₂ a Better Measure of PvCO₂ in Infants

Austin, Texas—Transcutaneous CO₂ (TcCO₂) more accurately reflects blood levels of the gas than end-tidal CO₂ (EtCO₂) in infants, according to investigators at Stony Brook University, New York.

Kseniya Khmara, MD, a clinical anesthesia resident at Stony Brook University School of Medicine, explained that the inaccuracies often observed using EtCO₂ because of the small tidal volumes inhaled by neonates motivated her team to investigate the efficacy of TcCO₂ as an
