Relationship between ETCO 2 and PaCO 2 under Changing Capnogram in Ventilated Infants with NAVA: An Observational Study

This observational study evaluated the validity of end-tidal CO (ETCO ) as a surrogate for arterial PCO (PaCO ) in infants on neurally adjusted ventilatory assist (NAVA), particularly considering the influence of variable spontaneous breathing on capnography waveforms. The study involved 16 infants,...

Description
Summary:This observational study evaluated the validity of end-tidal CO (ETCO ) as a surrogate for arterial PCO (PaCO ) in infants on neurally adjusted ventilatory assist (NAVA), particularly considering the influence of variable spontaneous breathing on capnography waveforms. The study involved 16 infants, analyzing 50 paired ETCO and PaCO values. Deming regression analysis highlighted a notably stronger correlation for maximum ETCO (r  = 0.6783, p
