Key result
In normothermic patients without significant pulmonary disease, PETCO2 correlated well with pulmonary artery blood flow (r = 0.88) during separation from cardiopulmonary bypass.
Why the study?
Does end-tidal carbon dioxide tension correlate with cardiac output during weaning from cardiopulmonary bypass in patients without significant lung disease?
Population
15 consecutive adult cardiac surgical patients without significant pulmonary disease, normothermic.
Design
Cohort
Follow-up
During and shortly after weaning from cardiopulmonary bypass

PETCO2 may track CO during CPB weaning in select patients; leaves open its role in guiding clinical decisions.

Does end-tidal carbon dioxide tension correlate with cardiac output during weaning from cardiopulmonary bypass in patients without significant lung disease?
Effect estimate: r = 0.88
In normothermic patients without significant pulmonary disease, end-tidal carbon dioxide tension is a useful non-invasive index of cardiac output during separation from cardiopulmonary bypass.
Maslow et al. (2001) conducted an observational in Cardiac surgery requiring cardiopulmonary bypass (n=15). End-tidal carbon dioxide tension (PETCO2) monitoring vs. Pulmonary artery blood flow (PAQt) and thermodilution cardiac output (TDCO) was evaluated on Correlation between PETCO2 and PAQt (r = 0.88). In normothermic patients without significant pulmonary disease, PETCO2 correlated well with pulmonary artery blood flow (r = 0.88) during separation from cardiopulmonary bypass.
