Why the study?
Do CardioQ and USCOM Doppler systems accurately track cardiac output changes and agree with each other in anesthetised patients undergoing major surgery?
Do CardioQ and USCOM Doppler systems accurately track cardiac output changes and agree with each other in anesthetised patients undergoing major surgery?
While CardioQ and USCOM Doppler systems can individually track changes in cardiac output during major surgery, they have poor precision and cannot be used interchangeably.
No takes yet. Share an insight, caveat, or question.
Poor precision precludes interchangeability of CardioQ and USCOM in major surgery; small cohort leaves open validation against reference standards.
Huang et al. (2014) studied this question.
