Pulse contour techniques should not replace thermodilution for tracking CO changes in cardiac surgery; leaves open need for device-specific validation.
Are arterial pulse contour techniques interchangeable with bolus thermodilution for assessing changes in cardiac output in cardiac surgery patients?
A novel trend interchangeability method demonstrates that five common arterial pulse contour techniques are not interchangeable with bolus thermodilution for tracking cardiac output changes during cardiac surgery.
