Uncalibrated pulse power analysis should not guide cardiac index decisions pre-CPB in CABG; leaves open calibration utility versus thermodilution.
Does arterial pulse power analysis accurately measure cardiac index compared to transpulmonary thermodilution in patients undergoing coronary artery bypass surgery?
Uncalibrated pulse power analysis is inaccurate for measuring cardiac output in CABG patients, and while calibration improves accuracy, it remains not consistently interchangeable with thermodilution.
