Supports HemoSonic CO monitoring in sedated post-cardiac surgery patients; leaves open accuracy in high-output states and operator dependence.
Does the HemoSonic monitor accurately measure cardiac output compared to standard thermodilution in post-cardiac surgery ICU patients?
The HemoSonic monitor provides cardiac output measurements that correlate well with standard thermodilution in sedated post-cardiac surgery patients, though it is less accurate in high cardiac output states and is operator-dependent.
