Key result
The Non-invasive Cardiac Output (NICO) monitor showed moderate correlation (r=0.691) with standard thermodilution, which yielded significantly higher cardiac output values (P=0.0003).
Why the study?
Does the Non-invasive Cardiac Output (NICO) monitor accurately measure cardiac output compared to the standard thermodilution technique in post-cardiac surgery patients?
Observational (n=12)
Does the Non-invasive Cardiac Output (NICO) monitor accurately measure cardiac output compared to the standard thermodilution technique in post-cardiac surgery patients?
Effect estimate: correlation coefficient 0.691
p-value: p=0.0003
The NICO monitor provides moderate correlation with thermodilution for cardiac output measurement but underestimates values, particularly in high cardiac output states, limiting its utility to specific mechanically ventilated patients.
No takes yet. Share an insight, caveat, or question.
NICO underestimation cautions against routine post-cardiac surgery use; leaves open validation in select mechanically ventilated patients.
Heerden et al. (2000) conducted an observational in Recent cardiac surgery (n=12). Non-invasive Cardiac Output (NICO) monitor vs. Standard thermodilution (TD) technique was evaluated on Cardiac output (correlation coefficient 0.691, p=0.0003). The Non-invasive Cardiac Output (NICO) monitor showed moderate correlation (r=0.691) with standard thermodilution, which yielded significantly higher cardiac output values (P=0.0003).
